Industrial noise pollution is a problem that many businesses experience. It also hurts neighbours and the environment. However, it is not an issue everyone has to put up with. For starters, doing this would put everyone’s health at risk. Secondly, there are specialist tools out there. They can minimise the noise that facilities create. Ventx is a business that tackles the sound by providing vent silencer models as well as various other designs.

Sound waves

You can think of sounds like the ripples in water when you throw a stone into it. The impact creates ripples which travel outward in each direction. Then, if you were to take this pool of water and squeeze it into a canal, these ripples would be channelled to flow through the canal’s length because they cannot escape the sides.

This is what occurs when you link your ductwork to a fan. Those sound waves originating from the fan are getting channelled through it. The ductwork functions as a barrier, stopping the sound waves from escaping outwards. However, there may be some breakout sounds.

Returning to the analogy, as the ripples move through the canal, they are still attempting to protrude outward in each direction. Some will fall on the walls of the canal or shore, producing a little noise. In the same way, breakout noise would be the sound waves attempting to escape via the duct.

The fan silencer’s role

It is here where a fan silencer comes into play. Installing one in the duct will aid you in absorbing a number of these sound waves. The quantity of them silencer’s absorb will depend on the acoustic media. Other factors that will influence this include the silencer’s length and its open area.

When sound waves enter silencers, the perforations existing in the baffle let them expand. It does this into the acoustic media. The material is comprised of millions of air pockets. When the sound waves impinge on them, it leads to the molecules moving and colliding with one another. That turns the sound energy into heat. It can then dissipate without noise.

The more baffles you are able to place within a silencer, the more noise you can reduce. At the same time, this will heighten the pressure drop. All fans generate pressure to push air forward. However, if there is an obstruction it can produce resistance in the air stream. So, a fine balance exists between the resistance of airflow the silencer creates and the pressure drop you can permit.
