Reliability, Accuracy & Efficiency of Automated Audiometry. (Publication)

This study investigated the reliability, accuracy and time-efficiency of automated pure-tone audiometry (air and bone conduction testing) using the KUDUwave™. This was done by comparing thresholds obtained through automated air and bone conduction audiometry using the KUDUwave™ with manually obtained air and bone conduction thresholds. The time it takes for each test method (automated vs. manual) was recorded during audiometry testing.

Validation of AC And BC Thresholds. (Research Report)

Air- and bone conduction thresholds obtained with the KUDUwave™ were compared with those obtained by the industry standard audiometer. Both these audiometers obtained thresholds inside a soundbooth.

Comparison of SDT, SRT and PTA. (Research Report)

SRT and PTA correlate well with an acceptable standard deviation. PTA and SDT correlate as expected with an acceptable standard deviation. The KUDUwave™ PTA, SRT and SDT correlate clinically with each other. The KUDUwave™ can confidently be used for Speech Audiometry.

Pure-tone audiometry outside a sound booth using earphone attenuation, integrated noise monitoring, and automation. (Publication)

This study investigated and reported on automated mobile audiometer with double-attenuation (increased attenuation) and real-time noise monitoring for use in clinical audiology testing without a sound booth. The KUDUwave™ was the device used in this study. Clinical validity was determined by comparing pure tone (air- and bone conduction) thresholds obtained by the KUDUwave™ inside and outside a sound booth.

Validation of KUDUwave™ Extended High Frequencies. (Research report)

The RETSPL values of ISO 389-5 cannot be used to do Extended High Frequency testing that is comparable with the the golden standards Sennheiser HDA200 earphones. The newly determined RETSPL values of the KUDUwave™ are comparable with the golden standards Sennheiser HDA200 headset calibrated to ISO 389-5. The EHF RETSPL values of the KUDUwave™ are 13.5 dB for 9000 Hz, 12.5 dB for 10,000 Hz, 21.5 dB for 11,200 Hz, 25.5 dB for 12,500 Hz, 32.4 dB for 14,000 Hz and 41 dB for 16,000 Hz.

Test-retest reliability of the KUDUwave™. (Research report)

The research was conducted to determine the test-retest reliability of the KUDUwave™ at all frequencies from 125Hz up to 16,000 Hz.

Validity of Diagnostic Computer Based Audiometer for AC and BC Audiometry. (Publication)

In this study, the air and bone conduction threshold results obtained with the GSI-61 audiometer were compared with thresholds obtained with the KUDUwave™ PC based audiometer. The test-retest reliability was also assessed and compared. This was done in order to validate the KUDUwave's air conduction and forehead bone conduction audiometry tests results. All tests were conducted in a sound-treated booth.

Validity of Diagnostic Pure Tone Audiometry Using A Portable Computerised Audiometer Without a Sound-treated Environment. (Thesis)

Historically diagnostic air and bone conduction audiometry has been conducted in conventional annually certified audiometric test booths that allow for testing of hearing thresholds down to 0 dB. Advances in technology with double transducer attenuation incorporating insert earphones with circumaural earcups and real-time on-screen monitoring of noise provide both passive control and active quantification of transient extraneous interference for testing outside of a booth.

Validity of diagnostic pure-tone audiometry without a sound-treated environment in older adults. (Publication)

This study aimed to investigate the validity of the use of the KUDUwave™ for diagnostic pure-tone audiometry in a natural environment. The KUDUwave used in this study uses the combination of insert earphones covered by circumaural headphones to attenuate ambient noise during audiometric testing. The device also incorporates real-time monitoring of environmental noise in order to notify the clinician if the ambient noise is masking the tone presented. The clinician in the study waited for the ambient noise to subside before continuing with the test.  .

Medical Surveillance Without a Sound Booth.  (Validation)

This research aimed to investigate the validity of the use of the KUDUwave™ for testing hearing threshold levels and monitoring the Percentage Loss of Hearing (PLH) in the occupational health setting for the purpose of medical surveillance of hearing without a sound booth. This study was conducted to answer the question: ‘’How do Kuduwave results compare with industry standard air conduction pure-tone audiometry?’’

Accuracy of Remote Hearing Assessment in a Rural Community. (Publication)

The study demonstrates the validity of using synchronous telemedicine for conducting hearing assessments with the KUDUwave™ in a remote rural agricultural community without a sound booth. The KUDUwave™ uses insert earphones covered by circumaural ear cups (Ambidome) to attenuate noise. The Ambidome provides noise attenuation similar to a single-walled sound booth.
