Attenuators have been designed to reduce noise interference between interconnected Space/Rooms. Airflow/Air-transfer is maintained at relatively low resistance whilst limiting high degree of noise transfer.
Four different styles are offered to suit most common configuration of installations.
Casings are manufactured from pre-galvanised sheet steel 1.2mm thick with Acoustic material infill lined with erosion resistance film which is retained and fixed with perforated sheet steel.
Acoustic performance of crosstalk attenuators are derived from tests meeting with requirements of BS4718:1971 and AS1191:1985.
