Absorption sound absorber for air conditioning plants and similar has webs or absorber panels of sound-absorbent material in gaps between absorbers in air channel

摘要

The device has absorbers of sound-absorbent material, located parallel at relative distances in an air channel. Webs (8) of a sound-absorbent material extending in flow direction, are positioned above each other in the gaps (5) between the absorbers (3). Alternatively, absorber panels in the gaps have apertures, which define flow channels. The gaps are covered at the top by a cover (6) of a sound-absorbent material, and at the bottom by a cover (7) of a smooth material.
