Sound masking is the inclusion of generated sound (commonly, though inaccurately, referred to as "white noise" or "pink noise") into an environment to mask unwanted sound. It relies on auditory masking. Sound masking is not a form of active noise control (noise cancellation technique); however, it can reduce or eliminate the perception of sound ...
Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio.
White noise masking has been well documented to reduce stuttering. [2] [10] [11] Clinic-based and portable devices, such as the Edinburgh Masker (since discontinued) have been developed to deliver masking, and found that masking was effective in reducing stuttering, [12] [13] though many found that reduction in stuttering faded with time.

White noise draws its name from white light, [2] although light that appears white generally does not have a flat power spectral density over the visible band. An image of salt-and-pepper noise In discrete time , white noise is a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean ...
This simple white noise machine offers ten fan sounds and ten ambient noise variations (including white, pink and brown noise). It is powered by either AC or USB and you can adjust the volume with ...
Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first.
Small and easily portable, this sound machine includes three sound options so you can find the right fit for you: bright white noise, deep white noise, and gentle surf. $19.99 at Amazon Restore 2 ...
Tinnitus maskers 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. [1] 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.
