Abstract
The purpose of the present study is to measure the sound spectrum of the underwater noise generated by a stern trawler M/S Saebada (2,275 GT, 3600 ps) in the various operational conditions. Underwater noises were recorded by a hydrophone (B & K 8100) and analyses were made rising a digital frequency analyzer (B & K 2131) and level recorder (B & K 2370). The predominant frequency range was 100-500 Hz, and maximum sound pressure level was 121 dB(re.
어선에서 발생되는 수중소음을 측정하기 위하여 선미식 트롤어선인 새바다호가 수심 100m인 제주도남쪽 해역에서 운항중일 때의 구중소음을 녹음 분석한 결과를 요약하면 다음과 같다. 1) 새바다호가 운항중일 때 주된 주파수대는
