AEROACOUSTIC NOISE REDUCTION OF AN AUTOMOBILE USING ACOUSTIC HOLOGRAPHY

  • 발행 : 2006.08.23

초록

This paper introduces the process of reducing the automobile wind noise by using acoustic holography. First, a microphone array scans a side or plane under an automible step-by-step. Second, a pressure on a source plane is calculated. Third process is to analyze how much individual sources contribute to interior noise. Fourth process is to control important noise sources determined by the contribution analysis. This paper deals with the entire process, theoretical and experimental problems.
