Reports on acoustic measurement tools

Mobile devices test results

The project partner EURECAT reports on the preparation of the mobile device for sound insulation measurements. A set of experimental measurements has been performed to compare the results between a Class 1 microphone and the smartphone.

Parametric loudspeaker

La Salle and University Ramon Llull performed experimental measurements for the design and testing of an omnidirectional parametric loudspeaker (OPL) prototype that generates audible sound through hundreds of ultrasound transducers set on a sphere.


EURECAT evaluated the use of mobile devices for airborne sound insulation measurements and developed a methodology for the application of these devices.
