Model 377A21 (cartridge) and Model 378A21 (cartridge and preamplifier system) are used in diffuse field applications and measure the entire human audible range and beyond. Accurate response is provided where high frequencies need to be measured precisely.
Ideal for aircraft and auto cabin noise measurements
Industry first 4Hz - 25kHz 1/2" random incidence microphone
Wide dynamic range - 22dBa to 150dB
APPLICATIONS:
Cabin noise (automobile and aircraft)
Environmental noise
White goods testing
Room acoustics
General, mid to high, amplitude noise measurements
