Sensitivity is an important indicator of the microphone's acoustoelectric conversion efficiency. It means that in a free sound field, the microphone output frequency is measured at a constant sound pressure of 1 kHz and in the positive direction of the sound source (that is, when the sound entrance angle is zero). The unit is mV / P. 1Pa = 10bar1ubar roughly equivalent to the normal human voice volume, measured at 1m distance sound pressure.
Microphone sensitivity is also useful decibel (db) said the provisions of 1 volt, Pa is 0db. As the sensitivity is much smaller than 1 V / P, so the sensitivity is a db.
BY-F8OD Professional omni directional lavalier video/instrument microphone
Boya BY-F8OD is a professional omni-directioanl Condenser lavalier video/instrument microphone, which not only perform well in video recording, but also works good for music recording. The frequency response favors the mid-range frequencies of group performance while minimizing noise registering at high and low frequencies. Omni directional pattern helps to pickup of sounds from all directions, make sure all sound clear and no details missed.
Microphone use different occasions, requiring the frequency response range and non-uniformity range is also different.
Dynamic microphone often do not take a flat frequency response curve, while in the high frequency (3 ~ 5KHz) a slight increase, which can increase pickup brightness and clarity. Generally speaking from the sound source is very close when used, there will be low-frequency boost phenomenon known as "talk about effect", so in the low frequency band below 150Hz is best to have obvious attenuation.
