This study is an experimental validation of a new closed-form method for automatic array position calibration, based on time of arrival (TOA) measurements between sources and sensors. An experiment with a large array composed of 121 microphones and a dozen of sources has been set up. We first show t…
This paper investigates the problem of estimating the shape or the boundary impedance of a vibrating membrane from acoustic measurements in a limited sub-domain of the membrane. In acoustics, polygonal room shapes are usually estimated through room impulse response measurements. Impedance values of…
We study the problem of microphone array localization in a strongly reverberant room, where time of arrivals (TOA) or time difference of arrivals (TDOA) cannot always be measured precisely. Instead, we use frequency-domain measurements to calibrate the array position, based on the modes of the room,…
