Description
Summary:Introduction: The problem of diagnosis and treatment of sensorineural hearing loss (SHL), including forms developed under the influence of noise, takes one of the leading places in ot­olaryngology. However, there are not many studies on acoustic trauma, although this problem has recently become more and more important. Objective: A comparison of subjective audiometry in patients with sensorineural hearing loss after acute acoustic trauma and chronic noise exposure. Materials and methods. In the work the results of exa­mination of 84 patients with acoustic trauma, 15 healthy as the control group and 15 workers employed on 'noise' occupations as a comparison group are given. Subjective audiometry was fully carried out by clinical audiometer AC-40 «Interacoustics» (Denmark). Hearing indices were investigated in the conventional (0,125-8) kHz and extended (9-16) kHz frequency bands. Results: Subjective audiometry showed a reduction in sound perception in all patients. Ac­cor­ding to the threshold tone audiometry in patients with acoustic trauma hearing thresholds were authentically (P
