Development of compact lowering ventilator noise equipment in fishing ship cabin
摘要
Abstract
In order to lower noise coming from ventilator in fishing ship cabin, compact lowering ventilator noise equipment was developed by means of absorb sound and lowering noise principle.Simulation and noise test have been done in laboratory, and the result was that ventilator noise was from 107 dB (A) down to 77 dB (A).A better result of lowering noise and absorbing sound was achieved.The equipment has these features of small size, simple structure, easy installation, low manufacture cost and so on.It provided a new method to lower working noise of ventilator in fishing ship cabin.关键词
