Standard Test Method for Laboratory Measurement of the Effectiveness of Floor Coverings in Reducing Impact Sound Transmission Through Concrete Floors

Standard Test Method for Laboratory Measurement of the Effectiveness of Floor Coverings in Reducing Impact Sound Transmission Through Concrete Floors

SIGNIFICANCE AND USE
5.1 The impact sound rating for a floor assembly is determined both by the basic floor assembly and the floor covering on the upper surface. The same floor covering in combination with different basic floor assemblies will not always give the same impact insulation class (IIC) ratings. This test method is designed to provide data that characterize the floor covering alone when installed over concrete slab floors.  
5.2 The ΔIIC rating calculated in 13.4 is used to compare the effectiveness of different floor coverings on concrete floors.  
5.3 The impact insulation class (IIC) calculated for the reference concrete floor with a covering provides an indication of the impact sound insulation that the covering will provide with typical, monolithic concrete floors.  
5.4 When the normalized impact sound pressure levels below a bare concrete slab are known, the difference spectrum calculated in 13.1 may be used to estimate the impact sound pressure levels and hence the IIC that would result if the covering were installed on the slab.  
5.5 Warning: Difference spectra measured using this method shall not be used to estimate impact sound pressure levels for floors comprising only one or two lightweight floor layers such as oriented strandboard or plywood. Such estimated impact sound pressure levels would be very inaccurate.
Note 1: The difference spectrum calculated in 13.1 gives unreliable estimates of the reduction in impact sound pressure levels due to the floor covering when it is placed on a joist floor incorporating a concrete topping (about 50 mm thick) poured directly on the plywood subfloor or steel deck. The estimated impact sound pressure levels are too low.3  
5.6 This test method closely follows that described in ISO 140-8 except that the single number rating used is the impact insulation class (IIC) described in Classification E989. The description of the standard concrete floor also differs.
Note 2: The requirement in Classification E989 that no devi...
SCOPE
1.1 This test method describes a method for the laboratory measurement of the effectiveness of floor coverings in reducing impact noise from a standard tapping machine through concrete floors. The test results are not necessarily directly related to the subjective evaluations of the floor coverings.  
1.2 This test method applies to all floor coverings, whether single or multi-layered, as installed on a standard concrete floor. Multi-layered coverings may be factory-assembled or assembled at the test laboratory.  
1.3 The test method applies only to laboratory measurements. It does not apply to the measurement of the effectiveness of a floor covering in a field situation.  
1.4 Laboratory Accreditation—A procedure for accrediting a laboratory for performing this test method is given in Method E492.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method

SIGNIFICANCE AND USE
5.1 Measurement of the sound absorption of a room is part of the procedure for other acoustical measurements, such as determining the sound power level of a noise source or the sound transmission loss of a partition. It is also used in certain calculations such as predicting the sound pressure level in a room when the sound power level of a noise source in the room is known.  
5.2 The sound absorption coefficient of a surface is a property of the material composing the surface. It is ideally defined as the fraction of the randomly incident sound power absorbed by the surface, but in this test method it is operationally defined in 4.2. The relationship between the theoretically defined and the operationally measured coefficients is under continuing study.  
5.3 Diffraction effects4 usually cause the apparent area of a specimen to be greater than its geometrical area, thereby increasing the coefficients measured according to this test method. When the test specimen is highly absorptive, these values may exceed unity.  
5.4 The coefficients measured by this test method should be used with caution because not only are the areas encountered in practical usage usually larger than the test specimen, but also the sound field is rarely diffuse. In the laboratory, measurements must be made under reproducible conditions, but in practical usage the conditions that determine the effective absorption are often unpredictable. Regardless of the differences and the necessity for judgment, coefficients measured by this test method have been used successfully by architects and consultants in the acoustical design of architectural spaces.  
5.5 Field Measurements—When sound absorption measurements are made in a building in which the size and shape of the room are not under the operator's control, the approximation to a diffuse sound field is not likely to be very close. This matter should be considered when assessing the accuracy of measurements made under field conditions. (See Te...
SCOPE
1.1 This test method covers the measurement of sound absorption in a reverberation room by measuring decay rate. Procedures for measuring the absorption of a room, the absorption of an object, such as an office screen, and the sound absorption coefficients of a specimen of sound absorptive material, such as acoustical ceiling tile, are described.  
1.2 Field Measurements—Although this test method covers laboratory measurements, the test method described in 4.1 can be used for making field measurements of the absorption of rooms (see also 5.5). A method to measure the absorption of rooms in the field is described in Test Method E2235.  
1.3 This test method includes information on laboratory accreditation (see Annex A1), asymmetrical screens (see Annex A2), and reverberation room qualification (see Annex A3).  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM E336-23(Test Method)
Standard Test Method for Measurement of Airborne Sound Attenuation between Rooms in Buildings

SIGNIFICANCE AND USE
5.1 The main part of this standard uses procedures originally developed for laboratory measurements of the sound transmission loss of partitions. These procedures assume that the rooms in which the measurements are performed have a sound field that reasonably approximates a diffuse field. Sound pressure levels in such rooms are reasonably uniform throughout the room and average levels vary inversely with the logarithm of the room sound absorption. Not all rooms will satisfy these conditions. Experience and controlled studies (1)6 have shown that the test method is applicable to smaller spaces normally used for work or living, such as rooms in multi-family dwellings, hotel guest rooms, meeting rooms, and offices with volumes less than 150 m3. The measures appropriate for such spaces are NR, NNR, and ATL. The corresponding single number ratings are NIC, NNIC and ASTC. The ATL and ASTC are measurable between larger spaces that meet a limitation on absorption in the spaces to provide uniform sound distribution.  
5.2 Annex A1 was developed for use in spaces that are very large (volume of 150 m3 or greater). Sound pressure levels during testing vary markedly across large rooms so that the degree of isolation varies strongly with distance from the common (separating) partition. This procedure evaluates the isolation observed near the partition. The appropriate measure is NR, and the appropriate single number rating is NIC.  
5.3 Several metrics are available for specific uses. Some evaluate the overall sound isolation between spaces including the effect of absorption in the receiving space and some evaluate the performance or apparent performance of the partition being evaluated. The results obtained are applicable only to the specific location tested.  
5.3.1 Noise Reduction (NR) and Noise Isolation Class (NIC)—Describe the sound isolation found between two spaces. Noise reduction data are based on the space- and time averaged sound pressure levels meeting the require...
SCOPE
1.1 The sound isolation between two spaces in a building is influenced most strongly by a combination of the direct transmission through the nominally separating building element (as normally measured in a laboratory) and any transmission along a number of indirect paths, referred to as flanking paths. Fig. 1 illustrates the direct paths (D) and some possible structural flanking paths (F). Additional non-structural flanking paths include transmission through common air ducts between rooms, or doors to the corridor from adjacent rooms. Sound isolation is also influenced by the size of the separating partition between spaces and absorption in the receiving space, and in the case of small spaces by modal behavior of the space and close proximity to surfaces.
FIG. 1 Direct (D) and Some Indirect or Flanking Paths (F and Dotted) in a Building  
1.2 The main part of this test method defines procedures and metrics to assess the sound isolation between two rooms or portions thereof in a building separated by a common partition or the apparent sound insulation of the separating partition, including both direct and flanking transmission paths in all cases. Appropriate measures and their single number ratings are the noise reduction (NR) and noise isolation class (NIC) which indicate the isolation with the receiving room furnished as it is during the test, the normalized noise reduction (NNR) and normalized noise isolation class (NNIC) which indicate the isolation expected if the receiving room was a normally furnished living or office space that is at least 25 m3 (especially useful when the test must be done with the receiving room unfurnished), and the apparent transmission loss (ATL) and apparent sound transmission class (ASTC) which indicate the apparent sound insulating properties of a separating partition including both the direct transmission and flanking transmission through the support structure. The measurement of ATL ...

Standard Practices for Mounting Test Specimens During Sound Absorption Tests

SIGNIFICANCE AND USE
4.1 The sound absorption of a material that covers a flat surface depends not only on the physical properties of the material but also on the way in which the material is mounted over the surface. The mountings specified in these practices are intended to simulate in the laboratory conditions that exist in normal use.  
4.2 Some of the specified mountings require special fixtures or minor deviations from normal practice. These fixtures or deviations are to be used only during laboratory tests and should not be specified for practical installations. They are noted in the specifications for the mountings in question by the phrase “for laboratory testing only.”  
4.3 Test reports may refer to these mountings by type designation instead of providing a detailed description of the mounting used.
SCOPE
1.1 These practices cover test specimen mountings to be used during sound absorption tests performed in accordance with Test Method C423.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM E1574-98(2023)(Test Method)
Standard Test Method for Measurement of Sound in Residential Spaces

SIGNIFICANCE AND USE
5.1 This is an in situ method, that is, the measurements are made at the actual installation. The sound levels measured according to this test method should be representative for that installation and for the quantity of acoustical absorption actually, permanently present.  
5.2 The test method has the following limitations:  
5.2.1 The test method produces sound data which may be compared with applicable criteria or limits only if they are in terms of the quantities measured in this test method.  
5.2.2 The test method does not quantify certain subjective aspects of the sound environment that may be objectionable. These include pure tones, spectral content, and temporal distribution.
SCOPE
1.1 This test method provides guidance to the methodology used in the measurement of building interior sound levels.  
1.2 This test method describes procedures for measuring sound in enclosed residential spaces produced by built-in utilities and major appliances such as plumbing, heating, ventilating, air-conditioning systems, refrigerators, and dish washers. The measured values may then be used to assess compliance, design, or habitation suitability.  
1.3 This test method does not promulgate or recommend acoustical criteria.  
1.4 This test method is not intended for obtaining data to evaluate indoor environments for:  
1.4.1 Commercial activities such as studios, communication centers, hospitals, and auditoria, and  
1.4.2 Effects from exterior sources such as aircraft, railroad operations, motor vehicles, mining operation, weapons fire, etc.  
1.5 This test method is not intended for evaluating sound transmission loss, sound absorption coefficient, or any other acoustical aspects of the space or structure.  
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
3.1 Definitions—Terms and related definitions given in Section 4 are intended for use uniformly and consistently in all building and environmental acoustic test standards in which they appear.  
3.2 Definitions of Terms Specific to Each Standard:  
3.2.1 As indicated in Section 4, terms and their definitions are intended to provide a precise understanding and interpretation of the building and environmental acoustic test standards in which they appear.  
3.2.2 A specific definition of a given term is applicable to the standard or standards in which the term is described and used.  
3.2.3 Different definitions of the same term are acceptable provided each one is consistent with and is not in conflict with the standard definition for the same term, that is, the general concept the term describes.  
3.2.4 If a standard under the jurisdiction of ASTM Committee E33 specially defines a term, i.e. provides a definition different in any way from what is given in Section 4 of Terminology C634, that standard shall list the term and its description under the subheading, Definitions of Terms Specific to This Standard.
3.2.4.1 Discussion—The mandatory language of section 3.2.4 is consistent with the mandatory language from §E2 of Form and Style for ASTM Standards (April 2020) and with the ASTM Committee E33 bylaws in place when this standard was published; it reflects a situation that exists, it does not prescribe anything.  
3.3 Definitions for some terms associated with building and environmental acoustic issues and not included in Terminology C634 are found in ISO/TR 25417 or IEEE P260.4. When discrepancies exist, the definition in Terminology C634 shall prevail.
SCOPE
1.1 This terminology covers terms, related definitions, and descriptions of terms used or likely to be used in building and environmental acoustics standards. Definitions of terms are special-purpose definitions that are consistent with the standard definitions but are written to ensure that a specific building and environmental acoustics standard is properly understood and precisely interpreted. The primary focus of this document is upon terms, definitions and descriptions found within standards under the jurisdiction of ASTM Committee E33; however, terms, definitions and descriptions that are of general interest to the field of acoustics are also included.  
1.2 This building and environmental acoustics standard cannot be used to provide quantitative measures.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM E492-22(Test Method)
Standard Test Method for Laboratory Measurement of Impact Sound Transmission Through Floor-Ceiling Assemblies Using the Tapping Machine

SIGNIFICANCE AND USE
5.1 The spectrum of the noise in the room below the test specimen is determined by the following:  
5.1.1 The size and the mechanical properties of the floor-ceiling assembly, such as its construction, surface, mounting or edge restraints, stiffness, or internal damping,  
5.1.2 The acoustical response of the room below,  
5.1.3 The placement of the object or device producing the impacts, and  
5.1.4 The nature of the actual impact itself.  
5.2 This test method is based on the use of a standardized tapping machine of the type specified in 8.1 placed in specific positions on the floor. This machine produces a continuous series of uniform impacts at a uniform rate on a test floor and generates in the receiving room broadband sound pressure levels that are sufficiently high to make measurements possible beneath most floor types even in the presence of background noise. The tapping machine itself, however, is not designed to simulate any one type of impact, such as produced by male or female footsteps.  
5.3 Because of its portable design, the tapping machine does not simulate the weight of a human walker. Therefore, the structural sounds, i.e., creaks or booms of a floor assembly caused by such footstep excitation is not reflected in the single number impact rating derived from test results obtained by this test method. The degree of correlation between the results of tapping machine tests in the laboratory and the subjective acceptance of floors under typical conditions of domestic impact excitation is uncertain. The correlation will depend on both the type of floor construction and the nature of the impact excitation in the building.  
5.4 In laboratories designed to satisfy the requirements of this test method, the intent is that only significant path for sound transmission between the rooms is through the test specimen. This is not generally the case in buildings where there are often many other paths for sounds— flanking sound transmission. Consequently so...
SCOPE
1.1 This test method covers the laboratory measurement of impact sound transmission of floor-ceiling assemblies using a standardized tapping machine. It is assumed that the test specimen constitutes the primary sound transmission path into a receiving room located directly below and that a good approximation to a diffuse sound field exists in this room.  
1.2 Measurements may be conducted on floor-ceiling assemblies of all kinds, including those with floating-floor or suspended ceiling elements, or both, and floor-ceiling assemblies surfaced with any type of floor-surfacing or floor-covering materials.  
1.3 This test method prescribes a uniform procedure for reporting laboratory test data, that is, the normalized one-third octave band sound pressure levels transmitted by the floor-ceiling assembly due to the tapping machine.  
1.4 Laboratory Accreditation—The requirements for accrediting a laboratory for performing this test method are given in Annex A2.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Impedance and Absorption of Acoustical Materials by Impedance Tube Method

SIGNIFICANCE AND USE
5.1 The acoustical impedance properties of a sound absorptive material are related to its physical properties, such as airflow resistance, porosity, elasticity, and density. As such, the measurements described in this test method are useful in basic research and product development of sound absorptive materials.  
5.2 Normal incidence sound absorption coefficients are more useful than random incidence coefficients in certain situations. They are used, for example, to predict the effect of placing material in a small enclosed space, such as inside a machine.  
5.3 Estimates of the random incidence or statistical absorption coefficients for materials can be obtained from normal incidence impedance data. For materials that are locally reacting, that is, without sound propagation inside the material parallel to its surface, statistical absorption coefficients can be estimated from specific normal acoustic impedance values using an expression derived by London (1).5 Locally reacting materials include those with high internal losses parallel with the surface such as porous or fibrous materials of high density or materials that are backed by partitioned cavities such as a honeycomb core. Formulas for estimating random incidence sound absorption properties for both locally and bulk-reacting materials, as well as for multilayer systems with and without air spaces have also been developed (2).
SCOPE
1.1 This test method covers the use of an impedance tube, alternatively called a standing wave apparatus, for the measurement of impedance ratios and the normal incidence sound absorption coefficients of acoustical materials.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Airflow Resistance of Acoustical Materials

SIGNIFICANCE AND USE
5.1 The specific airflow resistance of an acoustical material is one of the properties that determine its sound-absorptive and sound-transmitting properties. Measurement of specific airflow resistance is useful during product development, for quality control during manufacture, and for specification purposes.  
5.2 Valid measurements are made only in the region of laminar airflow where, aside from random measurement errors, the airflow resistance (R = P/U) is constant. When the airflow is turbulent, the apparent airflow resistance increases with an increase of volume velocity and the term “airflow resistance” does not apply.  
5.3 The specific airflow resistance measured by this test method may differ from the specific resistance measured by the impedance tube method in Test Method E384 for two reasons. In the presence of sound, the particle velocity inside a porous material is alternating while in this test method, the velocity is constant and in one direction only. Also, the particle velocity inside a porous material is not the same as the linear velocity measured outside the specimen.
SCOPE
1.1 This test method covers the measurement of airflow resistance and the related measurements of specific airflow resistance and airflow resistivity of porous materials that can be used for the absorption and attenuation of sound. Materials cover a range from thick boards or blankets to thin mats, fabrics, papers, and screens. When the material is anisotropic, provision is made for measurements along different axes of the specimen.  
1.2 This test method is designed for the measurement of values of specific airflow resistance ranging from 100 to 10 000 mks rayls (Pa·s/m) with linear airflow velocities ranging from 0.5 mm/s to 50 mm/s and pressure differences across the specimen ranging from 0.1 Pa to 250 Pa. The upper limit of this range of linear airflow velocities is a point at which the airflow through most porous materials is in partial or complete transition from laminar to turbulent flow.  
1.3 A procedure for accrediting a laboratory for the purposes of this test method is given in Annex A1.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Standard Test Method for Measurement and Reporting of Masking Sound Levels Using A-Weighted and One-Third-Octave-Band Sound Pressure Levels

SIGNIFICANCE AND USE
5.1 Acoustical performance is dependent on many factors (see Guide E1374 for a discussion on general office acoustical considerations). One of these factors is the masking sound. The masking spectrum shape and level must conform within specified tolerances throughout the treated area. The measurement and recording of these parameters are addressed in this test method.  
5.2 The results from this test method are used to determine if the masking sound meets a particular specification.
SCOPE
1.1 This test method specifies the procedure used to measure the masking sound in terms of A-weighted and one-third-octave-band sound pressure levels.  
1.2 The results of this test method can be used to determine if and where the masking sound meets (or does not meet) a particular specification.  
1.3 This test method does not evaluate the overall acoustical environment. It is intended only to measure and report the masking sound levels.  
1.4 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
