Acoustics, Noise & Vibration Monitoring

Noise and Vibration Monitoring for Compliance-Critical Projects

Noise and vibration are among the most common causes of regulatory action, community complaints and project disruption across construction, infrastructure and industrial operations. Where monitoring is required under Development Approvals, Environment Protection Licences or Environmental Management Plans, it must be technically defensible, properly interpreted and aligned with regulatory expectations.

Confluence Environmental delivers structured noise and vibration monitoring programs that support compliance, manage risk and protect project continuity across Sydney, Newcastle, the Central Coast and regional NSW.

Supporting Compliance, Risk Management and Project Delivery

Monitoring is typically required where works occur near sensitive receivers, regulated environments or critical infrastructure. It is commonly triggered by Development Application conditions, EPL requirements, Construction Environmental Management Plans and stakeholder risk controls.

Our role extends beyond measurement. We interpret results in the context of site activity, regulatory thresholds and project constraints to provide clear direction on compliance status, risk exposure and required mitigation. This ensures issues are identified early and managed before they impact approvals, programme or stakeholder confidence.

Environmental Noise Monitoring

We undertake baseline, construction and operational noise monitoring aligned with the NSW Noise Policy for Industry, project-specific criteria and local planning requirements. Monitoring programs are designed to reflect project risk and may include attended surveys, long-term unattended logging or targeted compliance monitoring.

Acoustic measurements including LAeq, LAmax and LCpeak are analysed in the context of background noise, meteorological conditions and operational activities to determine compliance and inform practical mitigation where required. Our monitoring supports infrastructure, construction, demolition and industrial projects where regulatory or community sensitivity is high.

Construction Noise and Compliance Monitoring

Construction noise monitoring is frequently required under planning approvals and Construction Environmental Management Plans. We develop monitoring programs aligned with work schedules and project risk, supported by structured reporting and exceedance management where required.

Where noise levels approach or exceed criteria, we provide clear mitigation guidance including operational controls, scheduling strategies and engineering measures. The objective is to maintain compliance while allowing works to proceed efficiently and without unnecessary disruption.

Vibration Monitoring and Structural Risk Assessment

Vibration monitoring is critical where works occur near buildings, utilities, buried services or sensitive infrastructure. Using calibrated geophones and accelerometers, we measure Peak Particle Velocity and vibration frequency to assess potential structural and human comfort impacts.

Monitoring is conducted in accordance with recognised standards including DIN 4150 and BS 7385, with interpretation based on building condition, ground response and vibration source. This provides early identification of risk and defensible documentation where structural or stakeholder concerns arise.

Vibration monitoring is commonly required for piling, compaction, demolition, excavation and major civil works.

Occupational Noise Monitoring

We also provide workplace noise exposure assessments to support SafeWork NSW compliance. Using personal dosimetry and static monitoring, we evaluate worker exposure against regulatory limits and provide practical control recommendations where required. This supports WHS obligations while integrating with broader environmental and project risk management.
