| Resumen: | |
| Keywords: | absorption; frequency response function; impedance; impedance ratio; impedance tube; normal incidence sound absorption coefficient; specific normal acoustic impedance; transfer function |
| Scope: | 1.1 This test method covers the use of an impedance tube, two microphone locations, and a digital frequency analysis system for the determination of normal incidence sound absorption coefficients and normal specific acoustic impedance ratios of materials. 1.2 Laboratory Accreditation— A procedure for accrediting a laboratory for performing this test method is given in Annex A1 . 1.3 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the use of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
