Pink noise generator

Velleman K4301: Pink Noise Generator Kit

Velleman K4301

DIY Pink Noise Generator Kit

The Velleman K4301 Pink Noise Generator kit is a powerful DIY tool to use along with a spectrum analyzer and a microphone to analyze the acoustic properties of your media room. Use a microphone with as linear of a frequency characteristic as possible (from 20Hz to 20kHz). If you have an equalizer, then the kit is even more useful as this allows you to not only see your systems performance, but you can also correct it. The circuitry is easy to modify to produce “white noise”.
