The Mars Microphone is one of the five measurement techniques SuperCam, an improved version ChemCam instrument that has been functioning aboard Curiosity rover for several years. SuperCam located on Rover's Mast Unit, to take advantage unique pointing capabilities rover's head. In addition being first record sounds Mars, can address original scientific objectives: study sound associated with la...

Performance analysis for microphone arrays with irregular geometries typically requires direct computation of beamforming gains over the spatial and frequency ranges of interest. However, theses computations can be very consuming and limit synthesis methods for applications that require rapid answers, as in the case of surveillance and mobile platforms. A better understanding of microphone arra...

A microphone position calibration method in a reverberant environment is investigated for randomly distributed large-size array in this paper. The microphone positions need to be known exactly in order to localize sound sources. Time delay estimation (TDE) is an important step in calibrating the microphone positions using a few calibrating sound sources for a randomly distributed array. However...

Microphone arrays are widely employed for applications like teleconferencing, high quality sound capture, speaker recognition/identification, acoustic surveillance, head aid devices, speech acquisition in automobile environments etc. For all these applications the benefits that a microphone array provides over a single microphone are two fold. First using a microphone array we can localize a so...

Embodiments of the present invention described and shown in the specification aid drawings include a combination responsive to an acoustic wave that can be utilized as a dynamic pressure sensor. In one embodiment of the present invention, the combination has a substrate having a first surface and an opposite second surface, a microphone positioned on the first surface of the substrate and havin...

Distributed microphone array (DMA) processing has recently been gathering increasing research interest due to its various applications and diverse challenges. In many conventional multichannel speech enhancement algorithms that use co-located microphones, such as the multi-channel Wiener filtering and mask-based blind source separation (BSS) approaches, statistics of the target and interference...
