Diagnostic Pure-Tone Audiometry In Schools: Mobile Testing Without A Sound-Treated Environment

Abstract Purpose: To validate diagnostic pure-tone audiometry in schools without a sound-treated environment using an audiometer that incorporates insert earphones covered by circumaural earcups and real-time environmental noise monitoring. Research Design: A within-subject repeated measures design was employed to compare air (250 to 8000 Hz)… Read More »Diagnostic Pure-Tone Audiometry In Schools: Mobile Testing Without A Sound-Treated Environment

Validation of a Bilateral Simultaneous Computer-Based Tympanometer

Abstract PurposeThis study aimed to investigate the accuracy of bilateral simultaneous tympanometric measurements using a tympanometer with two pneumatic systems inside circumaural ear cups. MethodFifty-two adults (104 ears), with a mean age of 32 years (SD = 12.39, range: 18–60 years) were included in this study. A… Read More »Validation of a Bilateral Simultaneous Computer-Based Tympanometer

Validity of Diagnostic Pure-Tone Audiometry Without a Sound-Treated Environment in Older Adults

Abstract Objective To investigate the validity of diagnostic pure-tone audiometry in a natural environment using a computer-operated audiometer with insert earphones covered by circumaural earcups incorporating real-time monitoring of environmental noise. Design A within-subject repeated measures design was employed to compare air (250 to 8000… Read More »Validity of Diagnostic Pure-Tone Audiometry Without a Sound-Treated Environment in Older Adults

Validity of Diagnostic Computer-Based Air & Forehead Bone Conduction Audiometry

Abstract Computer-based audiometry allows for novel applications, including remote testing and automation, that may improve the accessibility and efficiency of hearing assessment in various clinical and occupational health settings. This study describes the validity of computer-based, diagnostic air and forehead bone conduction audiometry when compared… Read More »Validity of Diagnostic Computer-Based Air & Forehead Bone Conduction Audiometry

One-eartip solution for pure-tone audiometry and acoustic immittance measurements: using insert earphone with an immittance probe ear tip

Abstract Objective Two consecutive studies sought to determine the (1) Equivalent Threshold Sound Pressure Levels (ETSPLs) and, (2) real ear attenuation thresholds (REAT) for the KUDUwave earcup configured with an insert earphone using a typical immittance probe tip (TPT). Design (1) Hearing thresholds were measured… Read More »One-eartip solution for pure-tone audiometry and acoustic immittance measurements: using insert earphone with an immittance probe ear tip

Pure-Tone Audiometry Outside A Sound Booth, Using Earphone Attenuation, Integrated Noise Monitoring, & Automation

Abstract Objective Accessibility of audiometry is hindered by the cost of sound booths and shortage of hearing health personnel. This study investigated the validity of an automated mobile diagnostic audiometer with increased attenuation and real-time noise monitoring for clinical testing outside a sound booth. Design… Read More »Pure-Tone Audiometry Outside A Sound Booth, Using Earphone Attenuation, Integrated Noise Monitoring, & Automation

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
