| چکیده | ||
| بی شک تولید صدا در قرن اخیر که از منابعی همچون سونارها، کشتی های باری نفتی، دستگاه های لرزه نگاری، اکتشافات حفاری نفت و گاز، شمع کوبی سازه های فراساحلی و غیره بسیار افزایش یافته است که این خود نوعی آلودگی است که آلودگی صوتی نامیده میشود .نویز صوتی باعث ایجاد استرس در حیوانات، افزایش ریسک در شکار شدن آنان و اختلال در سیستم زاد و ولد برخی گونه‌ها میشود. این اثرات می‌تواند تابع فرکانس و شدت صوت و مدت زمان مواجهه صوت باشد. برای اندازه گیری نویز شناور در آب‌های کم عمق شبیه سازی صوت جهت محاسبه افت انتقال بر طبق استاندارد امری ضروریست. در این تحقیق علاوه بر اندازه گیری میدانی نویز یک فروند شناور تندرو با استفاده از اصول استاندارد اندازه گیری، اثر امواج صوتی ناشی از شناورها و دیگر منابع تولیدکننده نویز صوتی در دریاها و اقیانوس ها بر جانوان دریایی برای گونه های مختلف بررسی شده است. در این پژوهش ابتدا منابع مختلف تولید نویزگردآوری می شود و تاثیر منابع مختلف صوتی بر زیست دریا و جانوران دریایی بیان می گردد و در قسمت بعد افت انتقال در محیط با شبیه سازی محیط محاسبه میگرددو درقسمت پایانی به اندازه گیری سطح نویز سه فروند شناورتندرو در سرعت های متفاوت می‌پردازیم و در نهایت برای کاهش نویز صوتی شناور تندرو پیشنهاداتی ارایه می‌نماییم. | ||

| چکیده [English] | ||
| No doubt the sound production in the last century has increased greatly from sources such as sonar, oil cargo ships, seismic devices, oil and gas drilling exploration, offshore pile-driving, etc. This is a kind of pollution called noise pollution. Noise can cause stress in animals, increase their risk of being hunted, and disrupt the reproductive system of some species. These effects can be a function of the frequency and intensity of the sound and the duration of the sound exposure. It is necessary to measure floating noise in shallow waters by sound simulation to calculate the transmission loss according to the standard. In this study, in addition to field measurement of the noise of a rigid buoy using standard measurement principles, the effect of buoyant noise waves and other sources of noise generation in seas and oceans on marine life for different species has been investigated. In this research, first, different sources of noise generation are produced and the effect of different sources of noise on marine and marine life is expressed. In the next part, the transmission loss in the environment is calculated by simulating the environment and in the last part, the noise level of the three fast crafts is measured. We deal with different issues and, finally, offer some suggestions for reducing the noise of the hard-hover. | ||
