Silencers – Acoustical enclosure

Silencers
Silencers 1000 mm or 2000 mm long are used to reduce the noise level below 75 dB(A). There are also suction hoods, chimneys, protective rain caps.
Acoustical enclosure (Acoustic booth)
Soundproof enclosures trap sound and prevent it from being transmitted outside. These are usually galvanized boxes covered with a foam layer with sound-insulating cells. The aim is to limit noise to 75 dB(A) at a distance of 1 m away from the machine. Many ventilators exceed these limits, so the use of a soundproof casing is necessary.
