교통소음의 음질 특성에 따른 불쾌도 감성변화에 대한 연구

A Study on Changes of the Annoyance Perception for Sound Quality Characteristics of the Traffic Noise

The A-weighting curve, very well explain the human perception for various frequency, is used to assess the traffic noise as well as the environmental noise. However, it does not reflect the annoyance perception appropriately because it assesses the noise at an A-weighted equivalent noise level of 1 kHz. In this study, we acquired the sound quality of traffic noise included various frequency and studied the human perception caused by change of frequency range.
