초록
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
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.
