A New Methodological Approach to the Noise Threat Evaluation Based on the Selected Physiological Properties of the Human Hearing System
A new way of assessment of noise-induced harmful effects on human hearing system is presented in the paper. The method takes into consideration properties of the selected physiological human hearing system. On the basis of the hearing examinations and noise measurements results and psychoacoustical noise dosimeter performance the new indicators of the noise harmfulness were proposed. The evaluation of the proposed indicators were conducted on the basis of hearing examination in the real noise exposure situations and also on the basis of the simulation results using standard test signals (such as: white, pink and brown noise). The performed analysis and obtained results confirmed the practical usefulness and correctness of the proposed indicators.
