Noise control in ICU is an important part of ICU decoration. Where should we control noise? First of all, we should know the source of noise in ICU!!
1. Air Transport Uncertainty
Operating room needs large air volume, small inlet and outlet, high wind speed and whistle. Therefore, in the design of air conditioning system for purification, the air supply rate in operating room should be determined accurately, and it can not be blindly applied to other engineering air volume values. At the same time, the air duct of laminar hood should adopt soft joint as far as possible.
2. Noise of air conditioning equipment
Because of the high resistance purifying air-conditioning system, the requirement of the residual pressure of the air-conditioning is high, and the noise of the operating room air-conditioning itself increases, because of the need to improve the fan power supply, resulting in increased noise in the operating room. Reasonable muffler can reduce the influence of air conditioning noise on operating room.
3. Laminar flow mask mesh plate
Because of the small effective area of the laminar hood mesh, such as the increase of air supply speed in the operating room, the noise will increase.
4. High Resistance Filter
Operating room and medium effect of HPF port have great resistance in the return port of air filter, which affects the effective area of air supply and return port to some extent, resulting in the increase of air supply and return speed and noise.
5. Noise of Rectifier
The sound of fluorescent lamp rectifier is poor, and the sound of strong current will appear in the process of using the rectifier, which will increase the indoor noise.
