About the direction of the microphone. Microphone directivity

By the angle of sound pickup or directivity, we mean the zone of the possible location of the source of the sound signal, inside of which there is no significant loss in microphone efficiency.

The direction of the microphone is the sensitivity of the microphone to sound, depending on the direction or angle from which the sound comes.

Microphones use several directivity characteristics. Usually they are depicted in the form of polar diagrams, in order to graphically display the sensitivity variations in the 360 ​​degree zone around the microphone, taking the microphone as the center of the circle, and putting the reference point of the angle in front of the microphone.

The radiation pattern shows the dependence of the sensitivity of the microphone to the sound signal on the location of its source.

By direction, there are three main types of microphones: Continue reading
