Recent studies show that pink noise is preferred in applications and environments that center around children because the decibel level is lower.
The first thing I did when Brian left was measure the speakers with what meager tools I had on hand: A Radio Shack sound meter, a CD of third-octave sinusoidal test signals, a spectrum analyzer, a second microphone, a pink-noise generator, and, to double check things, a CD of pink noise.
Also on the bill is Phantom Planet and Pink Noise Test.
