Overview
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.
