New Specification for Reverberation Room Requirements

1. Scope

This specification applies to ASTM standards within E33 that require the use of one or more reverberation rooms to evaluate the acoustical performance of a test specimen.


room modes; room average sound absorption coefficient; direct field; signal coherence


This standard is needed to harmonize the reverberation room requirements for all E33 standards the require a reverberation room, and it is anticipated that it will ultimately improve reproducibility between labs. The users would be all labs that perform testing in accordance with ASTM E33 standards.

The title and scope are in draft form and are under development within this ASTM Committee.
