The maximum permissible ambient noise and frequency-specific averaging time on the measurement of distortion product otoacoustic
There are two methods by which new born hearing screening is done -- otoacoustic
emissions (OAE) and automated auditory brain stem responses (BR).
Hearing screening is performed by one of two electronic tests, otoacoustic
emissions test (OAE) or auditory brainstem response (ABR).
Following the concert, the majority of the study participants also were found to have a significant reduction in the Distortion Product Otoacoustic
Emissions (OAE) test.
Cochlear function was assessed by pre-and post-noise (after 168 hours) recordings of distortion product otoacoustic
emissions (DPOAEs) and auditory brainstem responses (ABR).
Conventional audiometry and transient evoked otoacoustic
emissions were recorded before the application of the procedure and thirty minutes afterwards.
emissions are an excellent objective measure of cochlear health and are generally present when hearing thresholds are under 30 dB hearing level at each corresponding frequency measured.

Chapters cover aural immittance measures, otoacoustic
emission, electrocochleography, auditory brainstem response, and auditory steady-state response, and give recommendations for objective identification and diagnosis of hearing loss.
(2007) found that using pure tone audiometry testing as a single measure is not as sensitive as using otoacoustic
emissions testing, which identified hearing losses in 71% of the children, whereas pure tone audiometry only indicated hearing losses in 52% of the children.
