Sonic Acoustic Attenuator
Engineered Ventilation Noise Control Without Compromising Airflow
-
Backed by the Science of Silence
Powered by Flexshield
Manufactured by Flexshield, AcousTech Sonic acoustic attenuators are built in Australia using high-performance materials and controlled processes to ensure consistent acoustic and airflow outcomes.Trusted by engineers and built for performance
Engineers specify Sonic acoustic attenuators for their reliable noise reduction, pressure drop control, and integration into mechanical and ventilation systems across industrial and infrastructure projects.
