QUANTIFYING ACOUSTIC, MECHANICAL AND ELECTRICAL PHENOMENA OF A DEVICE FOR THE DETERMINATION OF SOUND-ABSORBING COEFFICIENT

Alin Cosmin TOT, Mariana ARGHIR

Abstract


This paper proposes a measurement of acoustic, mechanical and electrical phenomena encountered in a device for determining the coefficient of absorption materials, for the purpose of sizing audio frequency amplifier and adjust the level of electricity generated by it. This work is the continuation of a previous work in that it presents an impedance tube sizing, building its own laboratory, which is used in the thesis. The transformer has been designed and realized by the main author  under the guidance of the Director of doctoral studies, is designed to implement the compact or soundproofing materials provided with perforations, single or multiple compound.
