Noise has shape.
We draw it, then we quiet it.
From a motorway-facing bedroom to a development masterplan — Decibel maps the invisible architecture of sound and specifies the exact interventions that return quiet to your property.

We think in cross-sections
and contours, not brochures
Measure, don't assume
We deploy calibrated sound level meters at your boundary, bedroom, or garden for 24–72 hours. Night-time readings, wind direction, seasonal variation — all captured before a single recommendation is made.
BS 4142:2014 methodologyMap the shape of the problem
Noise has direction, diffraction, and material behaviour. We model propagation paths — over, around, and through every barrier — and produce a contour plan showing exactly where the problem is worst and why.
CadnaA propagation modellingSpecify the intervention
From acoustic glazing schedules to earth berm geometry, green wall species lists to HVAC enclosure design — every recommendation is material-specific, contractor-ready, and costed against the dB reduction it delivers.
NBS specification formatVerify with measurement
After installation, we return with meters. Every project in this gallery was post-measured. If the numbers don't match the specification, we find out why — at no additional cost.
Post-completion verificationMap your noise.
Start with a postcode.
Every survey begins the same way — we need to know where you are, what you hear, and when you hear it. The form takes four minutes. We respond within one working day with a scoping note and indicative fee.

Written specification of recommended interventions
"We had three acoustic reports from the developer claiming the noise was within limits. Decibel's independent monitoring showed they were measuring at the wrong time of day. The planning committee accepted our data."
