https://pubmed.ncbi.nlm.nih.gov/10943020/
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 …
