Random Noise Generator

The General Radio 1382 is a Random Noise Generator that can generate noise in one of three spectrums

• “White” noise – constant energy per cycle bandwidth
• “Pink” noise – constant energy per octave bandwidth
• “USASI” noise for calibrating sound level meters as specified in the USASI Standard S1.4

This type of signal is useful for room-acoustics studies, loudspeaker and microphone test, psychoacoustic tests, filter tests, crosstalk measurements, calibration checks on recording systems, and modulation of signal generators and test oscillators.
