In the family kitchen, the range hood is an essential equipment, which can keep the air in the kitchen fresh and reduce the harm of oil fume to human body. However, due to the special use environment of the range hood, it is easy to have the problem of excessive noise. The following is the related content of noise treatment of Ezhou range hood.

first of all, understand the causes of noise of range hoods. The main reason for the noise of range hood is the vibration and rubbing sound caused by the rotation of motor and impeller fan. In addition, the vibration and sound wave reflection of the air duct wall will also increase the noise.

In view of the above problems, noise can be reduced from the following aspects:

1. Choose a low-noise range hood. Before buying a range hood, you can refer to the noise parameters of the product and choose a product with less noise.

2. check whether the range hood is installed securely. If the range hood is not installed firmly, it will produce greater vibration and noise, so make sure that the range hood is installed firmly to avoid shaking.

3. Improve the aerodynamic design of the range hood. By adjusting the shape and size of the air inlet and outlet of the range hood, the airflow dynamics is optimized, and the air resistance and resistance are reduced, thus reducing the noise. In addition, the length of the air duct and the flared area can be increased, so that the air flow in the air duct is more stable and the noise is reduced.

4. add a silencer. For the range hood with insufficient original silencing materials, you can add silencing devices by yourself, such as adding office silencers and sound insulation pads in the air inlet and outlet pipes.

in a word, it is very important to reduce the noise of range hoods, which also plays an important role in protecting residents' health and family environment. It is necessary to control the noise of range hood through various methods in order to achieve the expected effect.
