Polar and Frequency ResponseFor this discussion, you will chart the frequency response and polar response of one of your microphones. Solve the following issues:1. What source signal will you use

Polar Response

Another factor contributing to a mic's unique response is its polar response; that is, how it responds to sound coming at it from different directions. A mic can either respond to changes in air pressure or in air velocity, or both. The extent to which a mic is velocity or pressure sensitive will determine its polar response. The more pressure-sensitive a mic, the more it will be omnidirectional; the more velocity-sensitive it is, the more it will tend towards a bi-directional response.

Omnidirectional

An omnidirectional mic will respond equally to sound coming from all directions. Because only one side of the diaphragm is exposed, the mic can only sense changes in air pressure, regardless of direction. Note, however, that even omnidirectional mics become more directional at the highest frequencies, responding better to sound coming from directly on-axis to (in front of) the mic that off-axis to (from the sides and especially behind) the mic. This is due to the body of the mic itself acting as a baffle.
