ASTM WK77042

Revision of C423-17 Standard Test Method for Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method

Keywords

None Provided

Rationale

Empty Room and Room with Specimen This has been on ongoing discussion among the task group. This working was determined to be the best option. Seems a lot of labs do this anyway though it is not specified in the standard to do so. Those labs that dont already do this do not see it as burdensome. In general, all see it as good laboratory practice and an improvement to the standard
