ASTM E2963-16

Standard Test Method for Laboratory Measurement of Acoustical Effectiveness of Ship Noise Treatments Laboratory Measurement of Acoustical Effectiveness for Marine Bulkhead and Deck Treatments

SIGNIFICANCE AND USE
5.1 To fully understand the effects of a given treatment, five acoustical factors (transmission loss, acceptance, radiation efficiency, absorption, and damping) must be characterized. For example, only knowing the effect of a given treatment on transmission loss will not allow the acoustical designer or engineer to assess its impacts on propagation of vibration (among other effects), which is an important path to consider for large machinery items and propeller excitation.  
5.2 It is necessary to have a common definition of acoustical performance and test procedure to determine all five acoustical factors for ship’s treatments so that the performance of different treatment types, as well as the same treatment type from different manufacturers, can be compared.  
5.3 In some cases, particularly for damping treatments, the effect of the treatment will be dependent on the non-treated structure’s material and geometry and other non-acoustic factors such as environmental conditions (that is, temperature). To fully characterize a treatment it may be necessary to test a range of base constructions. For reasons of practicality, convenience, or economy, it may be sufficient to test only one to three constructions to achieve an understanding of the material performance in a range of practical situations. Additional discussion is provided in Annex A1.
SCOPE
1.1 This test method covers the laboratory measurement of the acoustical effectiveness of treatments installed on ship bulkheads, decks, and side shells. Measurements are focused on assessing changes in transmission loss, radiation efficiency, and acceptance that occur when treatments are applied. Measurements of changes to absorption and damping are addressed in Appendix X1 and Appendix X2, respectively.  
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 and health practices and determine the applicability of regulatory limitations prior to use.  
1.4 Any material that is to be installed on a marine division must meet appropriate fire, combustibility, and other applicable SOLAS, USCG, IMO, Navy, or other required non-acoustical standards and specifications. See Appendix X3 for additional information.

INTRODUCTION
This test method is designed to measure the acoustical effectiveness of treatments that are intended
to reduce airborne noise on ships. Such treatments would be applied to compartment structural
partitions such as bulkheads, decks, and side shells. To fully characterize the acoustical performance
of a treatment, five parameters must be assessed: transmission loss, radiation efficiency, acceptance,
absorption, and damping. This test method focuses on the assessment of the first three, and provides
for convenient assessments of absorption and damping. Tests discussed in this method are based on
theTest Method E90 setup and procedure.This test method is not intended to be a replacement ofTest
MethodE90;conversely,thismethodbuildsontheE90methodthatisnowwellestablished.Similarly,
this test method does not replace absorption testing discussed in Test Method C423, nor damping
testing discussed in Test Method E756, though for reasons of convenience this method can be used to
make approximate assessments of how different treatments may impact these parameters.
