Quick Summary

In acoustics, noise is any undesired sound. White noise contains all audible frequencies at equal intensity, similar to white light. Pink noise also contains all audible frequencies but with intensity decreasing by three decibels per octave as frequency increases. This characteristic is similar to many musical instruments and natural sounds.

Coloured noise refers to noise with a wide spectrum but a greater intensity within a narrow band of frequencies. An example of coloured noise is the whistling sound of wind.12
