The Effect Of Cockpit Noise On The Temporary Threshold Shift Of Cessna 172sp Flight Instructors, Andrew Robert Bellini

Doctoral Dissertations and Master's Theses

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, resulting in permanent hearing loss. A result showing minimal to no temporary threshold shift would indicate that hearing personal protective equipment is working properly. This study used sound-level measurements, and audiometric testing, together with survey data to determine whether or not flight instructors were at risk for potential hearing impairment due to temporary threshold shift.
