Novel lightweight sound source for acoustic testing

Acoustic testing currently involves an expensive and hardly portable set of equipment.

In order to minimize cost and to make this technology more portable and automate its use, the capabilities of smartphones as acoustic receivers will be explored.

The aim is to develop a novel lightweight sound source for acoustic testing that provides a more diffuse field than standard loudspeakers and ensures easy portability and regulation compliance.

An indoor positioning method is being developed to tag the location of the acoustic measurements. This is based on Bluetooth Low Energy beacons. This novel methodology will reduce the cost of experimental tests and be more suitable for self-inspection.

On the other hand, a comparative characterization of the several build materials will be carried out in Eurecat laboratories.
