ASTM International - ASTM E2235-03

Standard Test Method for Determination of Decay Rates for Use in Sound Insulation Test Methods

Organization: ASTM International
Publication Date: 10 April 2003
Status: inactive
Page Count: 4
ICS Code (Acoustics in building. Sound insulation): 91.120.20
scope:

1.1 This test method covers the measurement of sound decay rate in rooms and the calculation of the sound absorption of the room and its contents. The sound absorption so calculated may be used in calculations in sound insulation test methods.

1.2 The method shall be used only in conjunction with other test methods where the logarithm of the sound absorption is used in formulas. It is not sufficiently precise for use in situations where room sound absorption is to be used without taking logarithms.

1.3 For laboratory measurements of the sound absorption of materials and objects, Test Method C 423 should be used.

1.4 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.
