Quality of Life Improvement by Early Detection of Hearing Loss Using High-frequency Audiometry: Extended high-frequency audiometry as a screening method

Abstract

The aim of the project is to compare hearing loss using high-frequency audiometry, to find a fast, cheap and simple screening method for hearing testing in adults. The project will contribute to more effective prevention, will develop recommendations and guidelines for a hearing loss screening. In the first year of the project, 253 persons aged 18-65 years were examined, out of the sample 69% were women. The age groups were divided into 5 categories from 18-24 and further by 10 years of age. The preliminary results (the data collection has not been finished yet) shows higher hearing loss in men comparing with women and significantly worse results for right ear (p < 0.05) in both sexes. Statistically significant difference in high-frequency hearing loss between men and women was confirmed especially in the oldest age group (p < 0.05). When comparing differences of hearing loss between the frequency 9 kHz and 14 kHz significantly higher loss was confirmed for the frequency 14 kHz for all age groups and also right and left ear (p < 0.01). Based on the preliminary results, increased hearing threshold values were found in relationship with frequency, sex and age in unexposed population.
