Hearwall turns acoustic test reports into something you can hear

Field notes

The proposed workflow starts with an accredited laboratory report rather than a generic acoustic curve. Hearwall says it checks 19-band one-third-octave transmission-loss data against STC and OITC methods, then applies the resulting filter to recordings such as aircraft, traffic, trains, and lawn mowers. Its package is aimed at the moment of sale: a branded single-file listening page, a mobile dealer module, and a report-linked Noise Profile. The site also describes an estimated-curve path when only rating numbers are available.
