Sound Attenuation in Audiometric Testing: A Review of Single-Walled Booths and Boothless Technologies for Occupational Hearing Screening

Abstract   This white paper investigates the sound attenuation performance of typical single-walled, small audiometric test booths and an emerging boothless audiometry system (Kuduwave), specifically focusing on the 125-8000 Hz frequency range critical for comprehensive occupational hearing screening. Accurate hearing assessment in workplace environments is… Read More »Sound Attenuation in Audiometric Testing: A Review of Single-Walled Booths and Boothless Technologies for Occupational Hearing Screening

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)

Establishing Maximum Permissible Ambient Noise Levels for the Kuduwave Audiometer: A Guide for Clinical, Research, and Proposed Unified Global Applications

Abstract Background: The accuracy of audiometric testing is critically dependent on a controlled acoustic environment to prevent ambient noise from masking test stimuli. Traditional sound-treated booths, while effective, present limitations in cost, portability, and accessibility. The Kuduwave audiometer is an innovative, portable diagnostic system designed… Read More »Establishing Maximum Permissible Ambient Noise Levels for the Kuduwave Audiometer: A Guide for Clinical, Research, and Proposed Unified Global Applications
