Abstract
The acoustical array composed of microphones and piezoelectric devices can reduce internally generated noise from the system such as a machine, a vehicle, or a robot. However, when the acoustical array combining microphones and piezoelectric devices is employed, it is necessary to estimate the gains of microphones and piezoelectric devices concerning the system that generates the noise in advance. The aim of this paper is to simplify this process, that is, to reduce internally generated noise without preknowledge concerning the gains of microphones and piezoelectric devices. Although the proposed method handles an anechoic mixing, it has some merits that complement the other typical blind source separation algorithms. In this paper, the problem is first formulated. The assumptions and the methodology of the proposed method are then given with some experimental results.
