Difference Between Omnidirectional Microphone And Unidirectional Microphone

Difference between omnidirectional microphone and unidirectional microphone

Let's take a look at the single directivity of microphones: The types of microphones can be broadly divided into four common types, which are almost met in our field of work. We now know or understand the types of microphones.

That is, the radio sensitivity is almost the same for both the front, rear, left, and right positions. However, it is an ideal physical environment. It is really behind the handle, that is, behind the sound head, there will be a little depression, and the frequency response will not be the same. (Acquisition of sound in different locations, and the related sound quality obtained, there will be very different;)

This is a matter of course, and is also the characteristic of most dynamic microphones, the "Dead Spot" (no radiation zone); in its reverse direction, 180 degrees, it is the deepest non-reaction zone, and therefore the sound signal coming from the rear of the sound head, It will not be picked up at all. This is also the most easily obtained physical characteristic of the general moving coil head technology. When the relative application is on the stage, when the monitor has a monitor behind the sound head, the impact value is very low. (Mainly used for teleconferencing, 3 or more microphone arrays are required, and the sound quality and effects obtained are relatively good;)

In order to respond sensitively to the audio pickup and fax, capacitive structure sounders are naturally born, and the feature of super-pointing (when the frequency is high, the long tail is behind the sound head) is a condenser microphone. All kinds of microphones are the most popular with the capacitive type, with the widest frequency response and flattest frequency characteristics. Although it is not shock resistant, it is prone to damp noises and extra power, but it is almost always a microphone of such characteristics in studios, radio stations, and live performances.

At present, the conference microphones produced by the United States source technology, In teleconferencing applications, foreign large-brand manufacturers are more common, mainly controlling the reverberation rate, sensitivity and sensitivity of each microphone, and require more advanced audio algorithms;

Through the second-generation audio coding (ALC, AGC, AEC, NR, NLP, etc.), Tenveo Mobile obtained a major domestic technological breakthrough in multi-channel microphone intelligent voice picking. Therefore, the Tenveo omni-directional microphone built into the array microphone ensures that you can use it to achieve better sound quality and presence.
