BSR 소음 재현을 위한 효과적인 음향합성법에 대한 연구

The BSR noise is induced by impacting or rubbing on each part, sound quality of BSR noise which mean as sound tone, interval and intensity is determined by material characteristics, assembly pattern and impact characteristic of paired parts. In this paper, it is suggested to generate real BSR noise by sound synthesis method to mix the virtual sound generated from the result of the transient analysis and the sound characteristic extracted from the specimen test as effect of material properties and environment change. It is conducted comparative study with real BSR sound and generated sound to improve the appropriateness of the BSR noise auralization method.
