Acoustic Louvred Doors and Gates
Acoustic louvre doors and gates are structures that use slatted louvres to control the transmission of sound while allowing airflow. These doors and gates are designed to reduce noise levels in environments where noise control is crucial, such as industrial facilities or power stations.
The louvres can be adjusted to balance the need for ventilation and sound reduction, making them versatile in various applications.
The primary objective of the design is to maintain a certain level of acoustic performance while allowing for necessary airflow and ventilation in the enclosed space.
