| Abstract:Taking the "Oriental Red No.3" vessel as an example, an effective noise control program was designed according to the fan room layout, the characteristics of fan noise to realize comprehensive control of fan noise. The principles of sound absorption, sound insulation and vibration isolation were adopted during the design. The test on board showed that this program can reduce noise obviously,decrease the influence of fan noise on scientific research instruments effectively ,and provide the crew with a comfortable working and living environment. |
