Microphone in Indirect Circuit

A biomimetic coupled circuit based microphone array for sound source localization.

An equivalent analog circuit is designed to mimic the coupled ears of the fly Ormia ochracea for sound source localization. This coupled circuit receives two signals with tiny phase difference from a space closed two-microphone array, and produces two signals with obvious intensity difference. The response sensitivity can be adjusted through the coupled circuit parameters. The directional chara...

Prediction of methane emission from beef cattle using data measured in indirect open-circuit respiration calorimeters.

The objectives of the present study were to examine relationships between methane (CH4) output and animal and dietary factors, and to use these relationships to develop prediction equations for CH4 emission from beef cattle. The dataset was obtained from 108 growing-to-finishing beef steers in five studies and CH4 production and energy metabolism data were measured in indirect respiration calor...

Paralinguistic Microphone

The Human vocal tract is considered for its sonorous qualities in carrying prosodic information, which implicates vision in the perceptual processes of speech. These considerations are put in the context of previous work in NIME, forming background for the introduction of two sound installations; “Microphone”, which uses a camera and computer vision to translate mouth shapes to sounds, and “Mic...

Microphone Arrays

Such techniques—known collectively as beamforming—have been the subject of intense interest in recent years within the acoustic array processing research community. Unfortunately, such techniques have been largely ignored in the mainstream automatic speech recognition field, although this may rapidly change given the recent release and widespread popularity of the Microsoft Kinect R © platform....
