Infrastructure projects carry acoustic obligations from the design stage, and the noise sources vary considerably by project type. Road and tunnel ventilation systems generate significant tonal noise from axial fans, often in constrained spaces with limited attenuation options and performance requirements locked into planning approvals. Pump stations and water infrastructure produce low-frequency noise that couples into structures and ground, travels considerable distances and responds poorly to standard attenuation products designed for mid and high frequencies.

Buildings with demanding internal acoustic requirements present a different set of challenges. Hospitals, courts, education facilities and government offices carry acoustic performance standards built into their function, not just their compliance obligations. HVAC systems, emergency generators and mechanical plant across large floorplates require careful source-by-source assessment and coordinated specification from early design. A gap between what the acoustic consultant has modelled and what gets installed is a common cause of post-completion disputes.

AcousTech works with engineers, contractors and facility managers across the infrastructure sector. We engage at the design stage to assess acoustic risk, model against regulatory requirements and specify systems backed by NATA-accredited test data. That approach reduces the likelihood of expensive remediation at practical completion, when acoustic sign-off is required and the options to address problems are limited.
