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)

Hearing Hoops: Dr. Anya Sharma’s Journey to Bring Audiometric Precision to the Underserved

  • Blog

The low, persistent hum of an old school generator was a stark contrast to the excited chatter of children outside a makeshift classroom. For Dr. Anya Sharma, an audiologist with a vision stretching far beyond city clinic walls, this was the frontline. Her mission: bring… Read More »Hearing Hoops: Dr. Anya Sharma’s Journey to Bring Audiometric Precision to the Underserved

The Conversion of Dr. Vance: How Rigorous Science Liberated an Audiologist from the Booth

  • Blog

Dr. Eleanor Vance was a bastion of audiological tradition. For over thirty years, her clinic, “Sound Perspectives,” thrived, built on meticulous care and an unwavering adherence to established protocols. Central to those protocols, almost a sacred space, was the sound-treated audiometric booth. To Eleanor, it… Read More »The Conversion of Dr. Vance: How Rigorous Science Liberated an Audiologist from the Booth

Advancing Audiometric Precision: Mastering Kuduwave’s SPHLin-ear with Standardised MPANL Correction Factors

Abstract Background: Ambient noise presents a persistent challenge to the accuracy of audiometric evaluations, particularly in settings outside traditional sound-attenuating booths. The Kuduwave audiometer is engineered to address this challenge through a sophisticated real-time ambient noise monitoring system. Objective: This white paper elucidates the interpretation… Read More »Advancing Audiometric Precision: Mastering Kuduwave’s SPHLin-ear with Standardised MPANL Correction Factors

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

Bringing Essential Hearing Care to Emergency Shelters and Community Centers with Kuduwave

  • Blog

During winter, community centers and emergency shelters experience a significant increase in demand as they provide essential services for vulnerable populations. For many individuals relying on these resources, accessing comprehensive healthcare, including hearing assessments, can be difficult due to logistical and financial barriers. Hearing loss, while often overlooked, can lead to social isolation, communication issues, and reduced quality of life. GeoAxon’s Kuduwave portable audiometer offers a solution, enabling audiologists to provide on-site hearing assessments directly in emergency shelters and community centers, where they are most needed.

With Kuduwave’s boothless, portable design, audiologists can bring high-quality hearing care to those who may have previously had little or no access. In these settings, where healthcare access is limited, Kuduwave is not just a tool; it’s a lifeline for community-centered care.
