It can be used for frequency response and phase calibration of measurement microphone. This equipment can significantly reduce the ambient noise to improve the signal-to-noise ratio, test accuracy and consistency.

The main component of CS022 is aluminum acoustic enclosure with 1/2-inch microphone fixed device. It has good sound insulation performance, and can be used to test 1/4-inch microphone by adapter. The electrostatic power supply can be connected to the interior of the acoustic enclosure through a 4 mm banana socket on the baseplate. In general indoor working environment, the internal background noise is approx. 10 dBA after the enclosure is closed.
