BS 8233 Noise Assessment — Internal Noise Criteria & Design Inputs
What BS 8233 Covers
BS 8233:2014 provides guidance on achieving appropriate internal and external noise levels for dwellings, hotels and other noise-sensitive buildings. We deliver surveys, analysis and design inputs so schemes meet target criteria for living rooms, bedrooms and outdoor amenity.
How We Help
Baseline surveys (day/evening/night) with Class-1 instrumentation
Façade calculations: glazing Rw/Ctr, composite elements and junctions
Ventilation strategy inputs (natural, MVHR, mixed-mode) to meet targets with windows closed where required
External amenity checks for gardens, balconies and communal spaces
Mitigation options: layout optimisation, barriers/screening, low-noise plant selection
Planning-Ready Deliverables
Survey method & results (LAeq,T, LAmax where relevant)
Internal/external criteria compliance tables
Façade and ventilation schedules with performance specifications
Marked-up drawings and clear, defensible recommendations
Typical Schemes
Residential new-build and prior-approval conversions
Mixed-use developments near roads or rail
Student accommodation and hotels
Fees
Pricing depends on site exposure, monitoring duration and façade/ventilation complexity. Call 01908 643433 for a fast estimate.
