The American National Standards Institute (ANSI) specifies maximum permissible ambient noise levels (MPANLs) allowed in an audiometric test room to ensure that hearing thresholds obtained down to 0-dB HL will not be elevated due to masking by ambient noise. MPANLs were originally specified in 1960 a …

Recently, the American National Standards Institute (ANSI) has specified (ANSI S3.1-1991) maximum permissible ambient noise levels (MPANLs) allowed in an audiometric test room that would produce negligible masking of pure tones presented down to O-dB HL for two test conditions (ears covered, ears not covered) and three test frequency ranges (125-8000 Hz, …
Ambient noise levels in industrial audiometric test rooms
https://pubmed.ncbi.nlm.nih.gov/8209846/
In 1983 the Occupational Safety and Health Administration (OSHA) specified maximum permissible ambient noise levels (MPANLs) that would allow valid hearing threshold measurements in an audiometric test room. However, ambient noise sound pressure levels (SPLs) in rooms used for industrial hearing tests are unknown. The present study reports …

The American National Standards Institute (ANSI) specifies maximum permissible ambient noise levels (MPANLs) allowed in an audiometric test room to ensure that hearing thresholds obtained down to 0-dB HL will not be elevated due to masking by ambient noise. MPANLs were originally specified in 1960 and have been revised in 1977, 1991, and most recently in 1999.
