Noise monitoring services are often required for a variety of purposes, ranging from environmental baseline quantification to operational compliance assessment. GHD has undertaken numerous noise monitoring exercises, ranging from operator attended noise measurements, long-term unattended noise measurement programs, and continuous construction noise compliance monitoring. GHD has conduct these exercises to address consent or compliance requirements for submission to council, NSW EPA, and various state regulatory authorities.
Underwater noise has the potential to cause temporary or permanent auditory damage to marine megafauna, such as whales and dolphins. GHD has the capabilities to undertake underwater noise monitoring and modelling, creating appropriate buffer zones to protect marine fauna from excessive noise, such as from marine construction works. These capabilities include:
- Baseline and compliance noise monitoring
- 3D underwater noise modelling
- REF and EIS underwater noise assessments
- Design of underwater noise mitigation measures
GHD’s acoustic camera has proven to be a valuable tool in noise when identifying faults for acoustic separation improvement. With the capability to visualize noise through its microphone array, it can pinpoint specific areas of fault, which can later be treated to improve acoustic performance. It has aided in highlighting flanking paths and acoustic leakage in building acoustics situations.
It is often the case that any development, operation or construction is situated un-isolated to adjacent sensitive receptors. This can lead to excessive vibration that is root cause to additional regenerative noise, structural integrity issues and human comfort health impacts. GHD has undertaken numerous vibration monitoring exercises in a variety of scenarios, including the following:
- Ongoing construction vibration monitoring
- Rail pass by sample vibration monitoring
- Industrial equipment and HVAC monitoring
