Innovative fibreless HVAC duct silencer based on microperforated elements

Optimizing the ductwork design of centralized air distribution systems for new buildings and retrofits : a holistic simulation-based approach

“…Larger ducts (i.e., where airflow runs at lower velocities) can diminish turbulence and noise levels, especially with the existence of bends. Villau et al [87] reported that acoustic insulation materials could lower noise levels by absorbing sound waves. Additionally, anti-vibration mounts and flexible connectors can be implemented to lower structure-borne noise and vibration [16].…”
