Acoustic louvres are commonly used in HVAC (Heating, Ventilation and Air Conditioning) systems or industrial applications where noise control is required. They are typically installed in ventilation openings such as air intake or exhaust systems to reduce the spread of sound while maintaining proper airflow.
The structure of a sound shutter usually includes a series of angled or inclined openings or baffles that redirect sound waves, causing them to scatter and lose energy. This scattering effect helps to reduce overall sound transmission. The specific design and configuration of sound louvres varies depending on the desired acoustic performance and application requirements.
