Auditory masking is used in tinnitus maskers to suppress annoying ringing, hissing, or buzzing or tinnitus often associated with hearing loss. It is also used in various kinds of audiometry, including pure tone audiometry , and the standard hearing test to test each ear unilaterally and to test speech recognition in the presence of partially ...
Simultaneous masking (also known as spectral masking) A compression algorithm can assign a lower priority to sounds outside the range of human hearing. By carefully shifting bits away from the unimportant components and toward the important ones, the algorithm ensures that the sounds a listener is most likely to perceive are most accurately ...
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 ...

Filters are used in many aspects of audiology and psychoacoustics including the peripheral auditory system. A filter is a device that boosts certain frequencies and attenuates others. In particular, a band-pass filter allows a range of frequencies within the bandwidth to pass through while stopping those outside the cut-off frequencies.
Masking threshold within acoustics (a branch of physics that deals with topics such as vibration, sound, ultrasound, and infrasound), refers to a process where if there are two concurrent sounds and one sound is louder than the other, a person may be unable to hear the soft sound because it is masked by the louder sound.
Psychoacoustic studies can deliver threshold criteria for various acoustic events and the resulting perceived sounds. The key is masking, that describes the effect that a sound produces into another simultaneous sound. Masking depends on the spectral composition of both masker and masking signal, and on other variations with time. The basic ...
A standard hearing aid may be used for tinnitus masking; the tuning and amplification characteristics are different than when one is used in compensation for hearing loss. A study by Jalilvand in 2015, showed that hearing aids instead of tinnitus maskers used to amplify sounds helped with the perception of tinnitus for veterans with blast ...
