pickup pattern การใช้

• The pocket-sized Mikroport incorporated a dynamic moving-coil cartridge microphone with a cardioid pickup pattern.
• If monitors are oriented at 180 degrees to the microphones that are their sources, the microphones should have a cardioid pickup pattern.
• The pair consists of an array of two of the same microphones that have a bi-directional ( figure 8 ) pickup pattern.
• The pickup patterns of the pair, combined with their positioning, delivers a high degree of stereo separation in the source signal as well as the room ambiance.
• For example, a microphone's pickup pattern illustrates its proportional response to an incoming sound from a given direction, and these patterns can be represented as polar curves.
• Directional microphones are used in live sound to maximize GBF . Directional microphones with cardioid and hypercardioid pickup patterns are designed with reduced sensitivity to the rear ( cardioid ) or to an angle between the side and the rear ( hypercardioid ).
• A cardioid microphone exhibits an acoustic pickup pattern that, when graphed in two dimensions, resembles a cardioid, ( any 2d plane containing the 3d straight line of the microphone body . ) In three dimensions, the cardioid is shaped like an apple centred around the microphone which is the " stalk " of the apple.
