Pink Noise

Pink noise is a type of audio signal that contains equal energy per octave or an equal amount of power in each frequency interval. It is a type of noise signal that sounds similar to white noise but with a slightly different frequency response.

Pink noise gets its name because it appears as pink on a spectrum analyzer, with a flat frequency response that rolls off at -3 decibels per octave. This means that the higher frequencies in the signal are slightly quieter than the lower frequencies.

In terms of how it sounds, pink noise has a soothing and calming effect on the listener. It has been used in various applications, such as sound masking, sleep aids, and meditation. When played through speakers or headphones, pink noise can create a consistent and relaxing background sound that can help block out distracting noises or promote relaxation.
