Defence environments present acoustically demanding conditions across a wide range of facility types, and the noise sources vary considerably. Large HVAC plant serving base infrastructure generates significant tonal noise from fans and cooling equipment. Maintenance bays and engine test facilities involve high-intensity broadband and impact noise. Weapons training areas carry a dual compliance burden: personnel exposure and community or environmental noise limits. Communications rooms often have stringent background noise requirements that conflict with the HVAC systems serving them.

AcousTech has worked across defence facility types and engages with the specific requirements of the Australian Defence Force infrastructure. We work to AS/NZS occupational noise standards and bring NATA-accredited system performance data to every specification.

Our work in defence covers:

• HVAC noise attenuation for base buildings and communications facilities
• Maintenance area treatment to reduce occupational exposure and support WHS compliance
• Weapons range noise control to meet both community impact limits and environmental conditions

In defence projects, procurement timelines and security requirements affect design approvals. Early engagement helps get the acoustic specification right before those constraints close off options.
