Every receptor, measurement and source pinned

Acoustic consultants, environmental health officers and planning consultants use Pin Drop for BS4142 and BS7445 measurements, receptor mapping and planning evidence.
Built for acoustic consultants

Noise surveys work better when every point is a pin

The shared map for noise surveys

A single BS4142 assessment can cover several measurement positions, a noise source and a handful of sensitive receptors. Consultants lose hours to field notebooks that get damp, photo libraries nobody can search and planning packs that take days to assemble. Pin Drop pins every measurement, source and receptor once and keeps every reading, photo and calibration record on the pin.
