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.
