Welcome to the noise generator page.
Random noise signals can be used for a wide range of purposes. One of the most common is to help block out other sounds. If you are trying to sleep but are disturbed by tinnitus, playing noise in the background can help to mask it. Likewise, noise is excellent at supressing muffled sounds that come through thinly walled rooms like those in university accommodation or office space. When listening to noise, many people are reminded of the sound of rainfall or waterfalls.
Online Tone Generator offers three flavours of noise: white, pink and brown. White noise has a flat spectrum, pink noise has a spectrum inversely proportional to its frequency, and brown noise has a spectrum inversely proportional to the square of its frequency. Each file lasts 30 minutes and is available to stream free of charge.
Many people have the opinion that new speakers and headphones benefit from "burn in". This is essentially where a user plays noise through their equipment for a prolonged period of time to slightly loosen the diaphragm reducing the harshness new speakers can sometimes have. Burn in is a hotly debated topic with some people staunchly defending it, while others say it is a waste of time. Why not try for yourself and see what you think?
