A polar pattern name typically used to describe microphone pick up characteristics. Hypercardioid patterns are similar to cardioid patterns in that the primary sensitivity is in the front of the microphone. They differ, however, in that the point of least sensitivity is at the 150 – 160 and 200 – 210 degree positions (as opposed to directly behind the microphone in a cardioid pattern). Hypercardioid microphones are thus considered even more directional than cardioid microphones because they have less sensitivity at their sides and only slightly more directly behind. Hypercardioid microphones are frequently used in situations where a lot of isolation is desired between sound sources.
