What is a bidirectional polar pattern?

What is a bidirectional polar pattern?

The bidirectional polar pattern (often referred to as figure-8) is symmetrically sensitive to sounds from the front and back while rejecting sounds to the sides. This basically means that both sides of the microphone diaphragm are equally exposed to external sound pressure.

How are polar coordinates used in microphones?

Audio technicians use graphs of polar coordinates to describe the functions of microphones. They give the pick-up area of the microphone in terms of polar equations. The microphone sits at the origin of the graph. The coordinates give the furthest distance that the microphone records sound in any direction.

What is bidirectional microphone?

A bidirectional mic, sometimes called a figure-of-eight, is equally sensitive to sounds coming from the front and rear of the mic and least sensitive to sounds coming from the sides.

Where is bidirectional microphone used?

Bidirectional microphones are used in applications where sound is recorded from the front of the micrphone and back of the microphone, but not the sides. An example of this is a Q&A lecture or presentation, where a professor gives a lecture to an audience and accepts questions from them.

What is a uni directional microphone?

Also known as a unidirectional or cardioid microphone, directional mics pick up sound from a specific area. Directional mics are designed to minimize unwanted background noise and has the highest pickup sound from the front, unlike omnidirectional mics which capture audio in every direction.

How do you use a bidirectional microphone?

What is bidirectional audio?

2-Way audio, or Bi-directional audio is a relatively new feature for many IP cameras, enabling the security operator not only to listen to sounds at the camera, but also to transmit audio to the camera.
