No. OSHA requires that the audiometric testing environment meet maximum permissible ambient noise levels (MPANLs) as specified in 29 CFR 1910.95 Appendix D — it does not mandate a physical sound booth. The booth is one method of achieving the required noise floor; it is not the requirement itself.
No. OSHA requires that the audiometric testing environment meet maximum permissible ambient noise levels (MPANLs) as specified in 29 CFR 1910.95 Appendix D — it does not mandate a physical sound booth. The booth is one method of achieving the required noise floor; it is not the requirement itself. Testing in a reasonably quiet room that passes an ambient noise check meets the same standard as testing in an engineered booth, provided the noise measurement is documented. This is a meaningful distinction for programs operating across multiple facilities or in environments where permanent booth installation is not practical. SHOEBOX: SHOEBOX PureTest performs a room scan before each testing session using an external microphone to measure ambient noise levels against OSHA MPANLs. The scan result — pass or fail — is stored with the audiogram record, providing documentation of the test environment for each session.
