Description: A good pink noise generator and a spectrum analyzer are indispensable if you want to analyze the acoustic properties of a room (usually a living room). Moreover, you also need a microphone with a frequency characteristic that is as linear as possible (from 20Hz to 20kHz). If you have an equalizer, then the response can not only be checked but also corrected. The kit is easily adapted to produce "white noise".
