When does a planning application need a noise assessment?

Local Planning Authorities require a noise assessment for a wide range of situations, such as:

Noise Impact Assessments for planning applications
Noise impact assessment for residential developments in accordance with BS 8233, ProPG, NPPF and other pertinent guidance
Internal noise validation for conditional discharge
Industrial noise assessments in line with BS4142
Commercial and retail noise impact assessments
Construction noise assessments in accordance with BS5228

If City of York Council has requested a noise or acoustic report, or if your planning permission carries an acoustic condition, we can help you meet it.

Meeting City of York Council's noise requirements

Residential development (ProPG and BS 8233)

For new residential development near roads, railways or other noise sources, City of York Council follows national NPPF policy and expects assessments prepared in line with ProPG and BS 8233. We assess external noise levels, provide internal noise predictions and specify the required facade treatments, including glazing, trickle ventilators and acoustic ventilation, to meet the criteria in habitable rooms and outdoor amenity spaces.

Commercial and mixed-use (BS4142)

Where commercial or industrial noise may affect residential receptors, or where new residential use is proposed near an existing commercial noise source, we carry out BS4142:2014+A1:2019 assessments. This is commonly required for mixed-use schemes, food and drink, retail and any development with external plant such as air conditioning units or condensers.

Construction noise (BS5228)

Where construction activities are proposed near occupied properties, we prepare a Construction Noise and Vibration Assessment in accordance with BS5228 and, where required, a Construction Noise Management Plan to satisfy City of York Council's pre-commencement conditions.

Condition discharge

Where planning permission has been granted subject to acoustic conditions, such as an internal noise validation or a plant noise assessment before occupation, we handle the discharge directly with City of York Council.

What a noise assessment from Opal Acoustics includes

Site survey and monitoring

Where the assessment requires measured noise data, we carry out a combination of manned and unattended noise monitoring at the site, capturing levels across the relevant day, evening and night-time periods. All equipment is calibrated and maintained in line with the relevant standard.

Assessment and report

We prepare the noise impact assessment with full reference to applicable planning policy and technical standards. Reports are written to be understood by both the planning authority and your project team, and are submitted in the format City of York Council requires.

Submission and follow-up

If the planning authority raises queries during determination, we respond directly. If acoustic conditions are attached to your permission, we handle the discharge. One point of contact throughout: a Director-level consultant, not a graduate with oversight.
