Used in laboratory and field enviorments for measurements in reverberant fields. Random incidence microphones provide uniform frequency response when sounds are coming randomly for all directions, as they are in a reverberation chamber.
The 46AQ is used for sound power level determination, sound transmission loss measurements and sound absorption measurements conducted in a reverberation chamber or other reverberant test environment.
BNC connection and CCP power is compatible with National Instruments data acquisition systems.
