Whadda pink noise generator.

A good pink noise generator and spectrum analyzer are essential if you want to analyze the acoustic properties of a room (usually a living room). In addition, you also need a microphone with the most linear frequency characteristic (from 20 Hz to 20 kHz). If you have an equalizer, the answer can not only be checked, but also corrected. The kit can easily adjust to produce "white noise". This text is machine translated.
