The sound absorption so calculated may be used in calculations in sound insulation test methods.<\/p>\n<p>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.<\/p>\n<p>1.3 For laboratory measurements of the sound absorption of materials and objects, Test Method C 423 should be used.<\/p>\n<p>1.4 <i>This standard does not purport to address all of the safety concerns, if any, associated with its use.
