Search for: [Abstract = "Noise\-induced hearing loss is the hearing loss caused by exposure to recreational and occupational noise. This is the second most common form of sensorineural hearing deficit, after presbycusis. The hearing loss depends on various factors, not only the acoustic parameters like sound intensity, frequency, time of exposure but also individual sensitivity. The hearing loss induced by harmful sounds is totally preventable, and avoiding noise exposure stops further progression of the damage. Because the individual sensitivity to noise is very differentiated, the avoiding of harmful sounds seems to be essential, especially in people exposed on potentially harmful sound levels in their workplaces. Therefore it is important to identify the universal audiometric test that might help in the screening of the early hearing impairment, in people especially sensitive to noise and people exposed to harmful sounds. Conventional audiometry between the frequencies 0.25\-8 kHz is a most common tool in the diagnosis of hearing loss. In the present study high frequency audiometry using sounds between 9\-20 kHz was applied to determine the early hearing loss in people exposed to harmful sounds. The aim of the present study was to determine the hearing threshold at 0.25\-20 kHz in healthy volunteers who were candidates for the noise exposed work. The evaluation of temporary and quantitative shift in thr"]
