A Scientific Critique of SANS 10083:2023 Section 15.1.2.3 Note 1: Rectifying an Impediment to Advanced Hearing Conservation Practices

Abstract   This white paper critiques Note 1 of Section 15.1.2.3 in the South African National Standard SANS 10083:2023, a standard for occupational noise and hearing conservation. This recently added note implies that if the sound-blocking capability (attenuation) of an audiometric device cannot be easily… Read More »A Scientific Critique of SANS 10083:2023 Section 15.1.2.3 Note 1: Rectifying an Impediment to Advanced Hearing Conservation Practices

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
