The Effect of Cockpit Noise on the Temporary Threshold Shift of Cessna 172SP Flight Instructors
<p>The purpose of this thesis was to study the temporary threshold shift of general aviation flight instructors resulting from their working environment. Exposure to noise before a temporary threshold shift completely recovers can cause a permanent threshold shift with no possibility of recovery, …

Hearing protection in mines : evaluating the Noise Clipper® custom made hearing protection device
… is seldom focused on the critical/biological thresholds for temporary threshold shift. Field studies on hearing protection devices have demonstrated that laboratory derived measures bear little relation to attenuation achieved in workers. Research has consistently demonstrated that noise …

Hearing Sensitivity and the Effect of Sound Exposure on the Axolotl (Ambystoma Mexicanum)
… AEPs were then performed to measure hearing thresholds immediately after sound exposure and at 2, 4, and 8 days post-sound exposure (DPSE). In the baseline audiogram, axolotls were most sensitive at 600 Hz, with an additional peak of sensitivity at 3 kHz. Following sound exposure, axolotls …
