Modern approaches to the diagnosis of occupational hearing loss in workers exposed to noise

Abstract

Due to the high prevalence of professional hearing loss, the difficulty of making decisions on the further working capacity of the employee, the issues of objectification of the assessment of the hearing condition among employees of «noise» productions, ensuring their reliability are very relevant. Based on the analysis of the results of tonal threshold audiometry and registration of short-latency auditory evoked potentials in 30 patients with impaired auditory function of professional origin, the difference in latencies of registered potentials, amplitudes and intervals was determined in comparison with a group of persons without industrial acoustic contact. The present study has shown that the test has sufficient informativeness in solving complex examination issues of interned patients with comorbid pathology of the circulatory organs by this age, and can be recommended for use for differential diagnosis of lesions of the central parts of the auditory analyzer in case of discrepancy with the results of tonal threshold audiometry.
