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 ...
In audio signal processing, auditory masking occurs when the perception of one sound is affected by the presence of another sound. [1] Auditory masking in the frequency domain is known as simultaneous masking, frequency masking or spectral masking. Auditory masking in the time domain is known as temporal masking or non-simultaneous masking.
White noise is a common synthetic noise source used for sound masking by a tinnitus masker. [10] White noise machines and other white noise sources are sold as privacy enhancers and sleep aids (see music and sleep) and to mask tinnitus. [11]
In speech communication, intelligibility is a measure of how comprehensible speech is in given conditions. Intelligibility is affected by the level (loud but not too loud) and quality of the speech signal, the type and level of background noise, reverberation (some reflections but not too many), and, for speech over communication devices, the properties of the communication system.
Masking can also happen to a signal before a masker starts or after a masker stops. For example, a single sudden loud clap sound can make sounds inaudible that immediately precede or follow. The effects of backward masking is weaker than forward masking. The masking effect has been widely studied in psychoacoustical research.
Nostril expanders “While nostril expanders do help for patients who may have some snoring, most of the snoring does happen in the back part of the throat so it is a false remedy for an ...
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.
Ted Bundy was born on Nov. 24, 1946, in Burlington, Vt., to single mother Eleanor Louise Cowell. She and her young son later moved to Tacoma, Wash., and she married John C. Bundy who adopted the ...
