Entries found for search: cardioid microphone

cardioid microphone : A directional microphone with an acceptance angle that is most sensitive to sounds coming from the front and sides, while rejecting sounds coming from the rear. Called cardioid because the polar pattern of the microphone is roughly heart-shaped. All directional mics have a proximity effect, whereby sound sources close to the mic will have an exaggerated low-frequency response. Supercardioids and hypercardioids are cardioids, but with a trade-off in the rear lobe. When using supercardioids and hypercardioids as sound reinforcement mics, it is important to note that the maximum rejection is not directly behind the mic as it is with a cardioid, but is off to the side between 110ĒŠ-126ĒŠ. However, a pair of hypercardioid microphones used as a stereo X-Y pair yields a very clean cardioid response pattern. See pressure gradient.

hypercardioid microphone : The narrowest of the unidirectional patterns, the hypercardioid is a variation on the cardioid microphone pick-up pattern which is most sensitive at the front and sides, while rejecting sounds entering 110°-250˚ to the rear, with a small lobe of sensitivity at 180˚ to the rear. The pick-up pattern of a hypercardioid is narrower than that of a supercardioid , and is somewhat similar to that of a figure-eight mic, but the response is asymmetrical in that the hypercardioid has greater sensitivity to sound arriving at the front of the capsule than to sound arriving a the rear. See acceptance angle. Also called a cottage loaf mic in the UK, for reasons related to bread.

supercardioid microphone : A variation on the cardioid microphone pick-up pattern which is most sensitive at the front and sides, while rejecting sounds entering 135°-225˚ to the rear. The supercardioid has a unidirectional pattern narrower than a cardioid, but wider than a hypercardioid. Also called a cottage loaf mic in the UK. See directional microphone.
