It is important to know where noise in your ventilation system is coming from, before you can reduce it. A ventilation system causes air to be moved and in doing so, vibrations are released. To do this, a mechanical ventilation system is equipped with a motor that also creates vibrations. Many of these vibrations produce noise and thus annoyance. The noise level can vary from one ventilation system to another.
