A visual depiction of white noise<unk> s are a range of devices based on simple white noise machines used to add natural or artificial sound into a tinnitus sufferer's environment in order to mask or cover up the ringing. The noise is supplied by a sound generator, which may reside in or above the ear or be placed on a table or elsewhere in the environment. The noise is usually white noise or music, but in some cases, it may be patterned sound or specially tailored sound based on the characteristics of the person's tinnitus. The perceived loudness of tinnitus, called sensation level (SL), is how much louder the tinnitus is above the ambient noise of the environment. By raising the ambient level of noise (playing white noise into the ear), the apparent loudness of tinnitus is reduced. The noise level is close to and usually somewhat louder than the perceived loudness of the tinnitus. The generated noise is designed to be a calming, less intrusive sound than the ringing or hissing of tinnitus. Depending on the loudness of the noise, tinnitus may be fully or partially<unk> . Tinnitus masking cannot reduce or eliminate tinnitus, only reduce awareness of it. The efficacy of a<unk>  may depend on the wearer's capacity to experience residual inhibition, the temporary suppression of tinnitus in response to particular sound patterns. The mechanism of sound masking can be explained by analogy with light. In a dark room where someone is turning a lamp on and off, the light will be obviously noticeable. However, if the overhead lights are turned on, turning on the lamp will no longer be as distracting because it has been "masked". While sound masking is an effective solution for a majority of those with tinnitus, it does not work for everyone.
