The NG-1 Audible Noise Generator provides both "Pink" or "White" noise and is a useful tool for broadband level matching of multiple microphones in studios, teleconferencing rooms and A/V installations. The NG-1 is an excellent source of background masking noise for injection into office background music systems or via direct acoustic radiation into small rooms.

The Pink Noise output of the NG-1 is optimum for measuring room response peaks and valleys when using a sound level meter in conjunction with a one-third octave response tuned voltmeter or analyzer. Either White Noise with equal energy per Hz bandwidth or Pink Noise with equal energy per octave of bandwidth is switch selectable. Pink Noise most closely matches the subjective loudness response of the ear and sounds uniformly loud at all pitches, whereas White Noise sounds very bright and lacking in low frequency content. The NG-1 incorporates a timer for pulse operation that interrupts the noise output for one second out of every four seconds so that the resulting signal picked up by the microphone can be readily distinguished from background acoustic and electronic noise. The NG-1 contains a built-in speaker or can drive external amplifiers and speakers. It is powered by an internal 9VDC battery (not included) for total portability or an AC/DC wall adaptor for continuous use. The device is housed in a rugged, compact ABS enclosure with swivel type mount.
