Pink Noise is much akin to "White Noise" whereas it contains all frequencies in the audible spectrum (technically it contains ALL frequencies, but normally further filtering removes the frequencies below 20hz and above 20khz for the sake of not damaging loudspeakers). However the distribution of energy is even across the frequencies, unlike white noise.
Pink noise is commonly used as a diagnostic aid in audio systems. It is a much more realistic signal to use than White Noise since music has much more energy in the low-end than the high-end.
It is important to avoid sending audio energy at frequencies outside of the range of your loudspeakers as this can damage them.
