As the time difference between the target and the mask increases, the masking effect decreases. This is because the integration time of a target stimulus has an upper limit 200 ms, based on physiological experiments [3] [4] [5] and as the separation approaches this limit, the mask is able to produce less of an effect on the target, as the target has had more time to form a full neural ...
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.
Masking (or the masking effect) is a visual style used in comics, first described by American cartoonist Scott McCloud in his book Understanding Comics: The Invisible Art. McCloud argues that characters with simple but recognizable designs, which he terms "iconic" characters, allow readers to project themselves into the story by using the ...
This reduces the effect of the masker by increasing the SNR. The above applies to the power-spectrum model of masking. In general this model relies on the auditory system containing the array of auditory filters and choosing the filter with the signal at its centre or with the best SNR.
When the ear is covered the subject hears body noises, such as heart beat, and these may have a masking effect. Minimal audible field and minimal audible pressure are important when considering calibration issues and they also illustrate that the human hearing is most sensitive in the 2–5 kHz range. [2]
So the masking threshold is the sound pressure level of a sound needed to make the sound audible in the presence of another noise called a "masker". This threshold depends upon the frequency, the type of masker, and the kind of sound being masked. The effect is strongest between two sounds close in frequency.
Auditory attention in regards to the cocktail party effect primarily occurs in the left hemisphere of the superior temporal gyrus, a non-primary region of auditory cortex; a fronto-parietal network involving the inferior frontal gyrus, superior parietal sulcus, and intraparietal sulcus also accounts for the acts of attention-shifting, speech processing, and attention control.
