Search for: [Abstract = "mented with application of high frequency tone, 14 kHz, the evaluation of the inner ear load measured with the return time to hearing levels was the same as in Peyser test, however included the high frequency pitches \(14\-20 kHz\). In cases with the presence of the shift, the evaluation of hearing threshold was preformed in 4\-minutes intervals, until the returning to the initial values. 4. The conventional audiometry was repeated after 8 years at noise exposed workplace. The comparative analysis of obtained results, was performed using the t\-Student test for parametric data and Mann\-Whitney test for non\-parametric data. All calculations were carried out with the use of STATISTICA software v. 7 \(StatSoft, USA\). Conclusions\: 1. In modified Peyser test following the application of high\-frequency tone, 14 kHz, the return time after 15s was observed in only 21.5% of study group. In the other 78.5% of study group the shift of return time ranged between 4\-24 min. In most of the studied cases \(47%\) the return time was 4 min. 2. The average values of the return time depended on the return time to initial values., In the study group, the return to initial values ranged between 20\-24 min, the average values of the return time shift ranged from 40\-60dB in 4.9% of examined cases. 3. The study group included young males, in 2nd and 3rd decade of life. Before the exposure to noise work the resp"]
