Abstract (en)

An individual-type or combined-type of high performance noise-canceling pickup with front and rear sound inlets that are roughly toward the same direction or perpendicular to each other is provided to be composed of a plurality of noise-canceling sensors. The noise-canceling performance of that pickup is much better than that of only individual-type noise canceling pickup with the sound inlets on the front wall of the front cover and the rear wall of the rear cover. Even in the extremely bad circumstances of high volume of noise, high signal/noise ratio can be still maintained so that voice is distinct. <IMAGE>
