LIFE15 ENV/IT/000268 NEREIDE:
“Noise Efficiently REduced by RecycleD pavEments”

iPOOL S.r.l. has collaborated in the development of the active control system of the positions of a PU probe for measuring the acoustic impedance of a floor mounted on a mobile laboratory. European project, in collaboration with the Department of Civil Engineering of the University of Pisa, ARPA Toscana, BRRC, ECOPNEUS, IDASC-CNR and the Region of Tuscany.

Specifically, IPOOL S.r.l. took care of:

 

  • Mounting on the vehicle of the stabilizer with adequate support structure
     

  • Housing of the sound absorption measurement system on the stabilizer
     

  • Anti-wind shield for the PV sensor
     

  • Realization of the power supply electronics of the PV sensor and of the acquisition system of the Pressure and Speed signals
     

  • Implementation of the software to trace the acoustic absorption curve from the acquired data with relative release of the software and schematic sourcesVerification of absorption curve correctness through normed measurements
