Sensitivity

Refers to the ratio of the open circuit voltage of the quality micphone AY-863 to the sound pressure acting on its diaphragm. In fact, the quality micphone AY-863 will inevitably cause sound field scattering in the sound field, so there are two definitions of sensitivity. One is the sound pressure that actually acts on the diaphragm, which is called the sound pressure sensitivity, and the other is the sound field sound pressure of the quality micphone AY-863 that is not placed in the sound field, which is called the sound field sensitivity. The sound field sensitivity is divided into free Field Sensitivity and Diffuse Field Sensitivity. Usually the sound pressure sensitivity is given by the quality micphone AY-863 for recording, and the sound pressure or sound field sensitivity is given by the quality micphone AY-863 for measurement.

Frequency response

It means that when the quality micphone AY-863 receives sounds of different frequencies, the output signal will be amplified or attenuated as the frequency changes. The most ideal frequency response curve is a horizontal line, which represents the output signal can directly represent the characteristics of the original sound, but this ideal situation is not easy to achieve. Generally speaking, the frequency response curve of the capacitive quality micphone AY-863 will be flatter than that of the moving coil type. The common quality micphone AY-863 frequency response curve is mostly high and low frequency attenuation, while the mid and low frequency is slightly amplified.
