Background: The possible role of cochlear function in tinnitus generation is still a matter of debate. To assess the role of outer hair cell dysfunction in tinnitus and its possible relationship with ultra-high frequency (UHF) hearing sensitivity, transient evoked otoacoustic emissions (TEOAE) and UHF hearing thresholds were investigated in normal hearing individuals with and withou...
Introduction: The sound pressure levels caused by work environment noise, along with the effects and ways of reducing it, are one of the most important issues in the manufacturing industry. Noise is the most common pollutant in the industrial environment, which can cause many disorders in various organs of the body, such as the auditory and vascular systems. This study aimed to investigate the ...
