A Comparative Analysis of Attenuation and Maximum Permissible Ambient Noise Levels for Audiometric Headsets

Abstract The accuracy of audiometric testing is fundamentally reliant on controlling ambient noise to prevent the masking of test stimuli. Various audiometric transducers, including supra-aural, circumaural, and insert earphones, as well as integrated headset systems, offer differing levels of passive sound attenuation. This white paper… Read More »A Comparative Analysis of Attenuation and Maximum Permissible Ambient Noise Levels for Audiometric Headsets

Determining OSHA-Compliant Maximum Permissible Ambient Noise Levels (MPANLs) for the Kuduwave Audiometer (Utilizing Foam Eartips)

Abstract:   This white paper investigates the determination of OSHA-compliant Maximum Permissible Ambient Noise Levels (MPANLs) for the Kuduwave audiometer when used with foam eartips. It reviews OSHA’s baseline MPANLs (29 CFR 1910.95 Appendix D, Table D-1) and the more current ANSI S3.1-1999 (R2018) standard,… Read More »Determining OSHA-Compliant Maximum Permissible Ambient Noise Levels (MPANLs) for the Kuduwave Audiometer (Utilizing Foam Eartips)
