Hulse, “Science” Auditory Scene Analysis addresses the problem of hearing complex auditory environments, using a series of Albert S. Bregman. In perception and psychophysics, auditory scene analysis (ASA) is a proposed model for the basis of auditory perception. This is understood as the process by which the human auditory system organizes sound into perceptually meaningful elements. The term was coined by psychologist Albert Bregman.

From this principle a full-fledged theory of non-chordal notes is developed. Explanations of Violations of Exclusive Allocation. Popular passages Page – Perception of temporal order in speech: While the initial research on this topic was done on human adults, recent studies auxitory shown that some ASA capabilities are present in newborn infants, showing that they are built-in, rather than learned through experience.

Since auditlry than one source can sound concurrently, a second domain of study is how concurrent activities retain their independent identities — the subject of stream segregation. Primitive segregation is a bottom-up process whereby streams are parsed according to the correlations of acoustical cues.

At the same time there is little or no perceived dissonance in example 1a. Views Read Edit View history. Other research has shown that non-human animals also display ASA. In practice, this means that most non-chordal notes will maintain close within-voice pitch proximity i.

Auditory scene analysis

Judgments of timing are more precise between notes anqlysis the same stream than between notes in separate streams. Auditory streaming entails two complementary domains of study.

The theory is illustrated in Figure from page Natural soundssuch as the human voicemusical instrumentsor cars passing in the street, are made up of many frequencies, which contribute to the perceived quality like timbre of the sounds. Up to a point, with a number of voices speaking at the same time or with background sounds, one is able to follow a particular voice even though other voices and background sounds are present.

The sound bregmna chimeric in the sense that it does not belong to any single environmental object. Journal of the Acoustical Society of America, Vol. Most sounds have a lineage or history.


Bregman suggests that there is some merit in the visual system expecting objects to behave in accordance with Newton’s first law regarding momentum. It may want the listener to accept the simultaneous roll of the drum, clash of the cymbal,and brief pulse of noise from the woodwinds as a single brgeman event with its own striking emergent properties. The term was coined by psychologist Albert Bregman. But sound sources have no reason to act this way: Currently, scientists are studying the activity audditory neurons in the auditory regions of the cerebral cortex to discover the mechanisms underlying ASA.

Retrieved from ” https: This can be done with chords where it can be heard as a ‘color’, or as the individual notes.

Second, Wright and Bregman argue that the existence of a good horizontal streaming permits the addition of non-chordal tones without suffering the penalty of undue dissonance. There is a long history of research pertaining to the formation of auditory images. Temporal Coherence in the Perception of Tone Sequences. In this case, when perceiving a chord, the amalgamated partials of a constituent chordal tone don’t really form a stream per sebut rather form a potential stream that is realized only with a shift of attention from chord to chordal tone.

Canadian Journal of Psychology, 27, Please help improve it or discuss these issues on the talk page. Hulse, “Science” Auditory Scene Analysis addresses the problem of hearing complex auditory environments, using a series of creative analogies to describe the process required of the human auditory system as it analyzes mixtures of sounds to recover descriptions of individual sounds.

Since the recognition of events depends upon the proper assignment of auditory properties to different sound sounrces, auditory streaming is fundamental to the process of scene analysis — which in turn is fundamental to music perception. The Perceptual Organization of Sound. Stumpf later retracted this explanation.

We also examine the question of whether ASA is innate by looking at research that has studied human adults using physiological methods, as well as research on human infants and on non-human animals. In schema-based streaming,fusion of the foreground elements does not automatically result in the collective fusion of background elements.

This presents their auditory systems with a problem: Intervals exhibiting simple frequency ratios are especially prone to tonal fusion Verschmelzung — and hence are perceived as being most consonant. Perception of a melody is formed more easily if all its notes fall in the same auditory stream.


One would have thought that location would provide the strongest cue in the construction of an ecological representation since one of the best generalizations that can be made about independent sound sources is that they normally occupy distinct positions in space. Among the differences classically shown to promote segregation are those of frequency for pure tonesfundamental frequency for complex tonesfrequency composition, source location.

Bregman has pointed out that the formation of an auditory stream is governed largely by this principle. There are several unexplored repercussions to this view. One of the most musically innovative ideas in the book is the theory of dissonance developed in conjunction with James Wright. But the world of sound is not merely a succession of momentary incidents. Passing notes, neighbor tones, suspensions, and anticipations all conform to these stringent streaming conditions — whereas appoggiaturas and escape tones conform less well to the pitch proximity constraints.

Huron’s Review of A. Bregman’s “Auditory Scene Analysis”

This page was last edited on 2 Augustat Breg,an doubt, this volume is destined to be a classic treatise in hearing sciences. However, unlike much of the hearing sciences literature, Auditory Scene Analysis deals with the type of higher level issues that begin to intersect significantly with truly musical concerns. However, none of the above researchers have pursued the topic with such sustained conviction and in such detail as Al Bregman.

In general, individaul sounds tend to coalesce into a single percept in proportion to the physical correlations shared by the parts. There is no mention of the Haas or Precedent Effect, or citing of the literature demonstrating surprisingly good monaural localization abilities.

They are derived from the following CD, which was packaged with a booklet of explanations: Philosophical Transactions of the Royal Society B: The book’s sheer length and technical detail is apt to intimidate many musician readers, but I cannot recommend this book too highly for serious scholars of music perception.

Sound reaches the ear and the eardrum vibrates as a whole.
