The Noise Measurement Method of the Multi-Sound Source in Reverberation Field wiht Wave-Guide
Reverberation 음장내 다수 소음원의 음파관을 이용한 소음 측정 방법
Abstract
A noise measurement method of the multi-sound sources in a reverberation field with wave-guide is developed by experimental method. In the reverberation field, it is very hard to measure sound level or noise spectra of a certain sound source, when many sound sources generate noise simultaneously with a small space between them. Flexible wave-guide(tube) was used to measure noise level in a reverberation field. One end of the tube is attached to a sound source and the other end is closed with an anechoic terminal. Detailed method of the measurement and the source of error was considered as well.
