Generating pink noise

  1. Interesting, about ten years ago I made a microphone which fit into an XLR connector… nothing amazing, but it was fun learning to make my own stuff.

    Interesting project, I will have to read up on it to see if it is true pink noise. Great link, thanks.

    As for white noise, it is all frequencies at the same amplitude. We perceive it to sound higher pitched because it generally takes more amplitude in the lower frequencies to hear, plus our ears are naturally tuned ( think of our frequency response ) to the vocal range of 2-ish kHz – 4-ish kHz. That is why we notice babies crying, which is not by accident.

  2. Oh, and to expand slightly, Pink noise is used to tune audio systems because it more closely follows our ear’s frequency response… though not perfectly.

  3. I think you got it a bit wrong there, pink noise is Decreasing in amplitude over the spectrum whilst white noise is stable. You usually achieve this by lowpass filtering white noise.

  4. SimplyNoise has a noise generator on their website (as well as an iPhone app) that generates white, pink, and brown noise.

    I have more sensitive hearing when I’m working grave shifts (still haven’t figured that one out), and listening to pink noise with headphones helps get rid of it. I found out about pink noise through this website:
