K4301 PINK NOISE GENERATOR A good pink noise generator and a spectrum analyser are indispensable if you want to analyse 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 equaliser, then the response can not only be checked but also corrected. The kit is easily adapted to produce "white noise". Specifications
