Acoustics, Noise & Vibration Monitoring

Professional monitoring services that help you manage construction impacts and meet approval requirements across NSW.

Why Noise and Vibration Monitoring Matters

Construction, demolition, and operational activities often generate significant noise and vibration. If left unmonitored, they can:

  • Breach DA or EPA licence conditions

  • Trigger community complaints and compliance actions

  • Cause property or structural damage

  • Delay or restrict construction activities

  • Impact health and wellbeing of workers and neighbours

Monitoring ensures you remain within acceptable limits and can respond proactively to risks.

Our Acoustic & Vibration Monitoring Services

We provide comprehensive acoustic and vibration services tailored to your site, activities, and regulatory obligations.

Environmental Noise Monitoring

  • Baseline and operational noise assessments

  • Construction and demolition noise tracking

  • LAeq, LAmax, and LCpeak measurements

  • Compliance with the NSW Noise Policy for Industry and local council standards

  • Real-time or attended monitoring options

  • Community and stakeholder reporting

Used for developments near residential areas, schools, hospitals, or sensitive zones.

Construction & Demolition Noise Monitoring

  • Monitoring required by Construction Environmental Management Plans (CEMPs)

  • Daily, weekly, or event-based reporting

  • Noise modelling and management plan integration

  • Exceedance alerts and mitigation guidance

  • Ideal for civil works, road upgrades, rail, demolition, piling, and excavation

Vibration Monitoring

  • Real-time and attended vibration monitoring using geophones or accelerometers

  • Measurement of Peak Particle Velocity (PPV) and acceleration

  • Structural damage and human comfort risk screening

  • Compliance with German Standard DIN 4150, British Standard BS 7385, or project-specific guidelines

  • Used near heritage buildings, utility assets, or vibration-sensitive infrastructure

Occupational Noise & Worker Exposure Monitoring

  • Workplace noise assessments for SafeWork NSW compliance

  • Personal dosimetry and static location monitoring

  • Comparison against the 85 dB(A) 8-hour LAeq and 140 dB(C) peak limits

  • Noise control recommendations and hearing protection guidance

  • Suitable for industrial sites, construction crews, and plant operators

Frequently Asked Questions (FAQ) – Acoustics, Noise & Vibration Monitoring

Q: When is noise and vibration monitoring required?

Noise and vibration monitoring is typically required when:

  • Your development is subject to DA conditions

  • You’re working near residential or sensitive receptors (schools, hospitals, heritage sites)

  • Your site activities involve demolition, piling, blasting, or excavation

  • You hold an Environmental Protection Licence (EPL)

  • Community complaints or council concerns arise

Monitoring helps demonstrate compliance, protect stakeholders, and avoid delays or penalties.

Q: What guidelines apply to noise monitoring in NSW?

Environmental noise monitoring in NSW must comply with:

  • The NSW Noise Policy for Industry (EPA)

  • Local council development conditions and planning controls

  • Any noise limits set under EPLs, CEMPs, or OEMP plans

We also reference Australian Standards (e.g. AS 1055) and any site-specific acoustic requirements.

Q: How is construction noise monitored?

Construction noise is typically monitored using calibrated sound level meters to measure:

  • LAeq (equivalent continuous sound level)

  • LAmax (maximum recorded level)

  • LCpeak (peak sound pressure for low-frequency noise)

Monitoring can be real-time, attended, or event-based — depending on the project and regulatory requirements.

Q: What is vibration monitoring and when is it needed?

Vibration monitoring measures ground movement caused by construction, traffic, or equipment. It is required when working near:

  • Heritage buildings or vibration-sensitive structures

  • Buried utilities or underground services

  • Occupied dwellings or commercial properties

We measure Peak Particle Velocity (PPV) and acceleration, typically using geophones or vibration sensors, and compare results against limits from DIN 4150, BS 7385, or project-specific standards.

Q: What happens if noise or vibration exceed limits?

If monitoring shows exceedances:

  • We notify you promptly and assist with mitigation advice

  • A formal exceedance report may be required for the EPA or council

  • We may adjust your monitoring program or update your CEMP/OEMP

  • Ongoing monitoring helps verify that control measures are working

Proactive monitoring helps manage complaints and maintain good stakeholder relationships.

Q: Can you help with occupational noise monitoring?

Yes. We conduct workplace noise assessments in line with SafeWork NSW requirements, including:

  • Personal dosimetry (worker exposure over a full shift)

  • Static noise surveys for specific tools or plant

  • Comparison against the 85 dB(A) LAeq,8h and 140 dB(C) LCpeak limits

  • Recommendations for hearing protection and engineering controls

Reports are suitable for inclusion in WHS risk assessments and site safety documentation.
