Our Noise Assessment and Survey Process
From the initial consultation to the final detailed report, our team provides accurate assessments using high-precision sound level meters for measuring through to industry-leading acoustics and noise modelling tools as part of the assessments.
Free Consultation
We assess your project’s requirements and identify the survey and assessment scope based on the planning proposal, current noise guidance and local authority requirements.
On-Site Noise Monitoring
Using professional sound level meters, we measure noise levels at the best locations to acquire the data needed to be able assess the specific proposal.
Data Analysis & Noise Mapping
We process, present and assess the measured data and use advanced acoustic modelling software (SoundPLAN) to create detailed noise contour maps when the project requires this.
Reporting & Recommendations
Our reports provide clear, understandable assessment conclusions and robust mitigation strategies to address local authority and EH noise concerns or planning approval conditions.
Noise Assessment & Survey Use Cases
Residential Noise Assessments
Before new residential developments can gain planning approval, noise levels from existing noise sources must be assessed to ensure future residents have an acceptable living environment, both inside and outside of their dwellings.
Our assessments evaluate transportation, industrial and commercial and other noise sources, in line with current standards and guidance.
We provide clear, understandable reports to support developers, architects and planning consultants in securing approvals for a range of developments from new residential to refurbishment and mixed-use projects.
Industrial and Commercial Noise Assessments & Surveys
Industrial and commercial facilities must ensure that their operations don’t cause excessive noise pollution, particularly when proposing to install new plant or processes that could impact on nearby residential areas.
Our industrial noise surveys assess plant noise, machinery, and operational activities, providing data and noise impact assessments using BS 4142 methodology and helps businesses design and implement effective noise control and mitigation measures.
Construction Noise Assessments
Construction noise may need to be monitored to ensure it doesn’t exceed permissible limits set by local authorities.
We conduct pre-construction baseline noise assessments and ongoing site noise monitoring to help developers comply with planning conditions, environmental regulations, and BS 5228 standards.
Our reports support applications and prevent potential objections related to noise impact.
