Residential Development Noise Guide

Assessments for New Residential Schemes

Developing new residential properties near existing noise sources, such as busy roads, railways, or commercial areas, requires careful acoustic planning. Local Planning Authorities demand noise impact assessments to ensure future residents are not subjected to unacceptable noise levels. We provide clear reports to guide your residential development through the planning process.

ProPG: Planning and Noise

For new residential developments, the Professional Practice Guidance on Planning & Noise (ProPG) is the standard framework. ProPG uses a two-stage approach: an initial noise risk assessment followed by a detailed evaluation of acoustic design.

Our ProPG assessments involve detailed baseline sound monitoring and 3D acoustic modelling. By engaging with us early in the design process, we can help optimize site layouts to naturally screen noise, reducing the reliance on costly acoustic glazing or mechanical ventilation later on.

BS8233: Sound Insulation & Noise Reduction

British Standard 8233 provides the target criteria for indoor ambient noise levels in habitable rooms (bedrooms and living rooms) and external amenity areas (gardens and balconies). We calculate the required sound insulation performance of the building envelope (glazing, trickle vents, and external walls) to ensure these stringent internal targets are met.

AVO Guide (Acoustics, Ventilation & Overheating)

Modern highly-insulated homes must balance acoustic control with thermal comfort. The AVO Guide details how to assess the noise impact on residents when windows are opened to mitigate overheating. Our holistic assessments consider both acoustics and ventilation strategies to ensure your development complies with both noise and thermal requirements.

Discharging Planning Conditions

If your residential scheme has already been granted planning permission subject to noise conditions, we provide the specific testing and verification reports required to formally discharge those conditions and allow construction or occupancy to proceed.
