	Illusory continuity of tones - Wikipedia, the free encyclopedia
		The illusory continuity of tones is the auditory illusion caused when a tone is interrupted for a short time (approximately 50ms or less), during which a narrow band of noise is played.
		Whether the tone is of constant, rising or decreasing pitch, the ear perceives the tone as continuous if the 50ms (or less) discontinuity is masked by noise.
		Because the human ear is very sensitive to sudden changes, however, it is necessary for the success of the illusion that the amplitude of the tone in the region of the discontinuity not decrease or increase too abruptly.

		The ascending tone is 2500 ms and from 422 to 2371 Hz, and the descending tone is 500 ms and from 1189 to 841 Hz.
		The duration of the pure tone preceded by the noise tends to be overestimated.

	Temporal masking - Wikipedia, the free encyclopedia
		Similar to simultaneous masking, temporal masking reveals the frequency analysis performed by the auditory system; forwards masking thresholds for complex harmonic tones (e.g., a sawtooth probe with a fundamental frequency of 500 Hz) exhibit threshold peaks (i.e., high masking levels) for frequency bands centered around the first several harmonics.
		Temporal masking should not be confused with the ear's acoustic reflex, an involuntary response in the middle ear that is activated to protect the ear's delicate structures from loud sounds.
		One example of temporal masking is the illusory continuity of tones, an auditory illusion wherein a tone is interrupted by a burst of static but is perceived by the listener to be continuous.

		The induction of continuity of sinusoidal tones was examined in some detail by alternating a tone with bandpass and band-reject noises having various spectral compositions as well as with sinusoidal tones with other frequencies.
		However, while Bregman (1990) accepted the reallocation principle for the restoration of tones and noises (which he called the "old-plus-new heuristic"), he considered that phonemic restoration was different, and corresponded to a special "schema-driven" stream segregation, in which a Gestalt-type closure was accomplished without the reallocation of auditory input from noise to speech.
		Each of the tones in the repeating sequence of ten sinusoids was replaced by a different 40-ms segment of stochastic noise.

		A Shepard tone is a sound consisting of a superposition of tones separated by octaves.
		When played with the base pitch of the tone moving upward or downward, it is referred to as the Shepard scale.
		The scale as described, with discrete steps between each tone, is known as the discrete Shepard scale, but, after Shepard, Jean-Claude Risset created a version of the scale where the steps between each tone are continuous, and it is appropriately called the continuous Risset scale or Shepard-Risset glissando.

	Top-Down Processing
		We use the terms tone model and timbre model in different meanings, the former referring to a model of a sound at a certain pitch, and the latter to the model of instrument characteristics that apply to its whole range of sounds.
		The term timbre alone means the distinctive character of the sounds of a musical instrument, apart from their pitch and intensity, `sound colour'.
		If our transcription system were just able to extract its tone models from the musical piece itself, it would be an efficient and general purpose transcription tool.

		He concluded that there is an important role for the spectral centroid—in cases where the tones formed a minor-third interval, both the overall spectral height and the distance between the individual tone centroids correlated negatively with "blend" as judged directly by musicians.

		He observed that the relationship between chord tones and chord roots is very similar to the relationship between overtones and fundamentals in complex tones.

		Those spectral components that are not reinforced by being matched with the top-down prototype read-out by the selected object's pitch representation are suppressed, thereby allowing another stream to capture these components.
		The model simulates data from psychophysical grouping experiments, such as how an upward sweeping tone create a bounce percept by grouping with a downward sweeping tone due to frequency proximity, even if noise replaces the tones at their intersection point.
		The model also simulates illusory auditory percepts such as the auditory continuity illusion, and the Deutsch scale illusion whereby downward and upward scales presented alternately to two ears regroup based on frequency proximity.

		Data are simulated from psychophysical grouping experiments, such as how a tone sweeping upwards in frequency creates a bounce percept by grouping with a downward sweeping tone due to proximity in frequency, even if noise replaces the tones at their intersection point.
		Qualitative explanations of illusory contours from translating terminators and plaid adaptation are also given.
		These processes include the learning of top-down expectations, the matching of these expectations against bottom-up data, the focusing of attention upon the expected clusters of information, and the development of resonant states between bottom-up and top-down processes as they reach an attentive consensus between what is expected and what is there in the outside world.

		Unnecessary chatter, or self-centred internal dialogue, continually creates a state of inattention, a hypnotic fixation on a limited observation/mind set by repeated internal firing of the neuronic circuitry associated with the hearing process.
		In terms of stopping this chatter, it must be observed and allowed to lose its primacy - but this must be practiced rather than thought about/discussed (the latter two just causing even more noise).
