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 devices are available from numerous manufacturers in many forms, for a variety of different uses, including audio testing, sound masking, sleep-aid, and power-napping. Sleep-aid and nap machine products may also produce other soothing sounds, such as music, rain, wind, highway traffic and ocean waves mixed with—or modulated by ...
A second class of algorithms work in the time-frequency domain using some linear or nonlinear filters that have local characteristics and are often called time-frequency filters. [ 30 ] [ page needed ] Noise can therefore be also removed by use of spectral editing tools, which work in this time-frequency domain, allowing local modifications ...
Audio masking graph. Suppose a listener can hear a given acoustical signal under silent conditions. When a signal is playing while another sound is being played (a masker), the signal has to be stronger for the listener to hear it. The masker does not need to have the frequency components of the original signal for masking to happen.
Industrial noise control is a subset of interior architectural control of noise, with emphasis on specific methods of sound isolation from industrial machinery and for protection of workers at their task stations. Sound masking is the active addition of noise to reduce the annoyance of certain sounds, the opposite of soundproofing.
The past few years has seen heightened awareness about diversity in the workplace, the importance of valuing cultural differences, and the idea that every employee should be able to bring their ...
The assertion is that the "analog sound" is more a product of analog format inaccuracies than anything else. One of the first and largest supporters of digital audio was the classical conductor Herbert von Karajan , who said that digital recording was "definitely superior to any other form of recording we know".
