Scope: HVAC Soundproofing from the heat pumps installed on the roof top of a shipping company’s building. The soundproofing structure with the metal noise barriers was designed and installed by our engineering team. In this particular acoustic project metal acoustic panels were used offering a soundproofing of Rw = 32.5 dB and sound-absorption in a wide range of audio frequencies.
Remarks: Soundproofing HVAC noise sources requires a lot of emphasis in the ergonomic and mechanical aspects at the designing stage. That is critical for the airflow, the maintenance and the mechanical operation of the HVAC unit.
