Novel sound measurement tools tested

Eurecat and La Salle tested the new acoustic tools at a construction site of the building contractor OHL in Madrid.

The new tools consist of: a novel parametric omnidirectional loudspeaker, developed by La Salle, which acts as the acoustic emitter; and a user-friendly mobile app, developed by Eurecat, which acts as the acoustic receiver.

The aim of the test was to take sound insulation measurements using the new tools and compare them to the standard procedure that uses a conventional sound level meter and a dodecahedron loudspeaker.

Preliminary results show that both techniques seem consistent.
