The entry and exit openings, through which a noisy air flow pass, are the most significant vulnerabilities for noise leakage.
HNA offers a variety of doors designed for reducing noise levels into rooms. Our doors are made of galvanized metal and are....
Typically, the noise source is in a closed compound having inlet and outlet air openings. These are the acoustic weaknesses which we must deal with. Silencers are structures which are located at the entrances to the compound of the noisy air (room, canopy, wall, pipe, tube). ...
Acoustic Cells
When the noise source exists in an open space we can house the source in an acoustic cell. There are several types of acoustic cells, but the common denominator is insulating the source of the noise using a canopy...
