The aim of the study was to obtain and compare psychoacoustic audiological quantitative parameters in normal trained hearing and normal no-trained hearing persons. Study purposes were: to obtain and compare the statistical values of the air conduction hearing thresholds at the conventional frequencies (250-8000 Hz) and HF (9000-16000 Hz) in the tested groups; to estimate and compare speech range (500,1000,2000 Hz) and HF range (9000-16000 Hz) the statistical values of the hearing thresholds in the tested groups; to obtain and compare free field speech reception threshold’s (SRT – 50% speech perception, dB SPL) quantitative values in the tested groups.
Analysis of our study is based on investigation and estimation quantitative parameters of 73 persons with normal hearing. Testing group (T) consisted of 18 (data of 36 ears) musicians with normal trained hearing. They had more than 8 years every day special musical training. The control group (T) consisted of 55 persons with normal no-trained hearing, but with any musical graduation. Subgroup A consisted of 37 persons (data of 74 ears). Subgroup B consisted of 18 totally blind persons (data of 36 ears). Our results showed, that normal trained hearing is better.
