A analysis on the Sound of Passenger Cars by Sound Metrics

음질 지수를 이용한 자동차 실내 소음의 분석

Previously, we have analyzed Vehicle interior noise by dBA based analysis. However, dBA based analysis can not describe the various sound phenomenon that consumer hear. Sound quality matrics can describe various sound phenomenon that dBA based analysis could not explain. In this paper, we will demonstrate the difference of between dBA based analysis and real sound feeling, and analyze sound examples by sound metrics and Principle Component Analysis. In this way we can analyze vehicle interior noise more effectively.
