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

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
