(Test Method)Standard Test Method for Field Measurement of Tapping Machine Impact Sound Transmission Through Floor-Ceiling Assemblies and Associated Support Structures
Standard Test Method for Field Measurement of Tapping Machine Impact Sound Transmission Through Floor-Ceiling Assemblies and Associated Support Structures
SIGNIFICANCE AND USE
5.1 The spectrum of the noise produced in the receiving room by the standard tapping machine is determined by (1) the size and the mechanical properties of the floor-ceiling assembly, such as its weight, surface properties, mounting or edge restraints, stiffness, and internal damping; (2) the degree of flanking transmission through associated structures; and (3) the acoustical response of the receiving room.
5.2 The standardized tapping machine specified in 6.1.1 produces a continuous series of uniform impacts at a uniform rate on a floor-ceiling assembly to allow accurate and reproducible measurements of impact sound pressure levels in the receiving room. The tapping machine is not designed to simulate any one type of impact, such as male or female footsteps or to simulate the weight of a human walker. Also, measurements described in this method and ratings based on the results are restricted to a specific frequency range. Thus the subjectively annoying creak or boom generated by human footfalls on a limber floor-ceiling assembly may not be adequately evaluated by this test method.
5.3 Laboratory Test Method E492 calls for highly diffuse sound fields and the suppression of flanking sound transmission in the laboratory’s receiving room. This field test method does not allow efforts to suppress flanking. In field tests, acoustical measurements are much more uncertain than in the laboratory since a great variety of receiving room shapes and sizes are encountered in ordinary buildings. Highly diffuse fields are seldom found and the nature of structure-borne flanking transmission can vary widely. In addition, energy can be transmitted laterally away from the receiving room. The amount of lateral transmission of energy can vary significantly between buildings. Consequently, good agreement between laboratory tests and field tests on similar floor-ceiling assemblies should not be expected.
5.4 Several metrics are available for specific uses:

SCOPE
1.1 This test method covers the measurement of the transmission of impact sound generated by a standard tapping machine through floor-ceiling assemblies and associated supporting structures in field situations.
1.2 Measurements may be conducted on all types of floor-ceiling assemblies, 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 defines several procedures and metrics to assess either the apparent performance of the nominally separating floor-ceiling or the isolation of a receiving room from the sound produced by the operation of the tapping machine. The receiving room may be the space directly below the tapping machine or, in some cases, any separated space that receives sound from the operation of the tapping machine. The source and receiving rooms as well as the floor-ceiling system are identified and described in the test report. All measured levels and derivative single number ratings include the effect of flanking transmission. Efforts to suppress flanking are not permitted. Available measures and their single number ratings are the impact sound pressure levels (ISPL) and impact sound rating (ISR), the reverberation time normalized impact sound pressure levels (RTNISPL) and normalized impact sound rating (NISR), and the absorption normalized impact sound pressure levels (ANISPL) and apparent impact insulation class (AIIC).
1.4 The ISPL and ISR may be measured and reported between any two specific rooms or usage areas where the source room area is large enough to accommodate the tapping machine positions and the receiving room volume is sufficiently large to accommodate the microphone positions. For all other measures and ratings in this standard, restrictions such as minimum room volume or dimensions or maximum room absorption are imposed. Thus, conditions ...

INTRODUCTION
This test method is part of a set of standards for evaluating the sound insulating properties of
building elements and sound isolation between spaces. It is designed to measure in the field the impact
sound isolation between rooms or to estimate lower limits for impact sound transmission through a
floor-ceiling partition element installed as an interior part of a building using a standard tapping
machine. Others in the set cover measurement of impact sound transmission through an isolated
floor-ceiling assembly in a controlled laboratory environment (Test Method E492), the measurement
of airborne sound transmission loss of an isolated partition element in a controlled laboratory
environment (Test Method E90), the measurement of airborne sound isolation and airborne sound
transmission loss associated with building elements in the field (Test Method E336), the measurement
of sound transmission through building facades and facade elements in the field (Guide E966); and the
measurement of sound transmission through a common plenum between two rooms in a controlled
laboratory environment (Test Method E1414).
1. Scope
1.1 This test method covers the measurement of the transmission of impact sound generated by a standard tapping machine
through floor-ceiling assemblies and associated supporting structures in field situations.
1.2 Measurements may be conducted on all types of floor-ceiling assemblies, 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 defines several procedures and metrics to assess either the apparent performance of the nominally
separating floor-ceiling or the isolation of a receiving room from the sound produced by the operation of the tapping machine. The
receiving room may be the space directly below the tapping machine or, in some cases, any separated space that receives sound
from the operation of the tapping machine. The source and receiving rooms as well as the floor-ceiling system are identified and
described in the test report. All measured levels and derivative single number ratings include the effect of flanking transmission.
Efforts to suppress flanking are not permitted. Available measures and their single number ratings are the impact sound pressure
levels (ISPL) and impact sound rating (ISR), the reverberation time normalized impact sound pressure levels (RTNISPL) and
normalized impact sound rating (NISR), and the absorption normalized impact sound pressure levels (ANISPL) and apparent
impact insulation class (AIIC).
1.4 The ISPL and ISR may be measured and reported between any two specific rooms or usage areas where the source room
area is large enough to accommodate the tapping machine positions and the receiving room volume is sufficiently large to
accommodate the microphone positions. For all other measures and ratings in this standard, restrictions such as minimum room
volume or dimensions or maximum room absorption are imposed. Thus, conditions may exist that will not allow RTNISPL (NISR)
or ANISPL (AIIC) to be determined.
1.5 Where a separating floor-ceiling assembly is composed of parts that are constructed differently on the receiving room
(ceiling) side, it is not possible to determine the ANISPL and AIIC of the individual elements or portions of the assembly. In this
situation, the measurement will be of the composite structure, not of an individual element.
