How to effectively decrease the noise of ventilation system.

During the installation of the ventilation fan system, we often face this situation which is after the installation, the noise and air flow in bedroom and study room are kind of high, for those elderly people or those people who are very sensitive to noise, this will affect their sleep badly. The worse thing is, even you know the noise is unbearable for the ventilation system, but you will still need to open it, so this becomes a very intractable issue, so how to solve the noise from the ventilation system becomes a serious topic, but, eventually, we found the solution.

First, to chose the right and suitable ventilation products.

The ventilation system is using a persistent ventilation mode, the structure inside the ventilation product and the motor selection will ensure the persistent service time, in this case, it can continuously ventilating the air, although it might can’t be the same effects for short terms ventilating comparing with opening the window directly, but this continuous ventilation can reduce the polluted air from outside and can maintain the temperature inside the house. So, to choose the right ventilator, it must be according to the national regulations, no need for a very large air flow, in this case the noise will be lower, however, you could choose the super silent AMX brand ventilators, then you can solve the noise problem once for all, and most importantly, the air flow is also very astonishing. Also, as for AMX Fan, we have been in this business for more than 20 years, what we can provide is not just the products, but also the complete designs and solutions for your house, and everything could be customized.

Second, the rational design for air pipes.

When designing the ventilation systems, the air pipes overall arrangement should be considered in the first place, then the balance between air pressure and air speed from every air outlets, if the air pressure difference is huge, to adjust the air outlet rigidly will only rise the noise, especially in bedroom and study room, or if it is too close to the main ventilator, we suggest to choose circumvent design or sound-muffling pipe to connect the joint.

Third, suitable remediation after installation.

If still can’t sole the noise problem after the ventilation system is installed, and the pipeline is also adjusted, then we will have to work out some remediation, such as.

1.To change the hardware hanging of the main ventilator to spring hanging, to decrease the noise from the main ventilator as lower as we can.

3、To coat another silencer cotton at the ceiling surface, this will decrease the noise echo from the installation area between main ventilator and the ceiling, this will decrease the resonance between them also.

4、To add some silencer cotton at the turning or the air inlets, to add some windage in order to decrease the air flow, and obstruct the noise.

5、To change the pipe material into aluminum flexible pipe in the section with more noise, add the length of the pipe appropriately, and to add some windage at the turning, this will effectively decrease the noise.

With the help of these process, products selection, design and remediation, we could adjust the noise within a normal standard, or if you have more efficient way to decrease the noise, you are most welcomed to share with us.
