The Psychoacoustic Check: A Preferred Method for Audiometric Room Quietness Certification in South African Occupational Health

AbstractThis white paper advocates for the adoption of an Psychoacoustic Check as the preferred, scientifically robust, and practical method for verifying audiometric room quietness in South African occupational health settings. Traditional physical sound level measurements (e.g., SANS 10182) for room certification, particularly for mobile units,… Read More »The Psychoacoustic Check: A Preferred Method for Audiometric Room Quietness Certification in South African Occupational Health

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

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
