Description
VELLEMAN K4301Pink Noise Generator Kit Overview 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". Features

None greasy and smells wonderful
This product works really well and is not greasy at all. I found this product when we were travelling in Hawaii and I wanted more. I also love the smell.
