Complex sounds and critical bands.
Studies of the responses of human observers to bands of noise and other complex sounds have led to the measure of what appears to be a basic unit of hearing, the critical band. When the frequency spectrum of a stimulating sound is narrower than the critical band, the ear reacts one way; when the spectrum is wider, it reacts another way. For example, experiments show that at values less than the...
متن کاملComplex Sounds and Auditory Images
In recent years, there has been a growing interest in the perception of complex sounds, and a growing interest in models that attempt to explain our perception of these sounds in terms of peripheral processes involving the interaction of neighbouring frequency bands and/or more central processes involving the combination of information across distant frequency bands. In this paper we review the...
متن کاملComplex motion of precipitation bands
Formation and dynamics of an Al(OH)3 precipitation ring is studied by diffusing NaOH into a gel containing AlCl3. Limited feeding of the outer electrolyte (NaOH) is found to yield an intricate ring-dynamics which involves stopping and reversal of the direction of motion of the precipitation ring, and evolution into stationary multi-ring structures. A model of the ring-dynamics is developed by c...
متن کاملCortical processing of complex sounds.
Work on the functional organization of auditory cortex in nonhuman primates has recently gained increasing attention. Neurophysiological studies using complex stimuli, combined with anatomical tract tracing, reveal a hierarchy of cortical processing comparable to other sensory systems. On the basis of these findings from animal studies, together with the advent of modern neuroimaging methods us...
متن کاملAdditivity of loudness across critical bands: a critical test.
The use of magnitude estimation as well as axiomatic measurement theory has led to the suggestion that loudness adds across critical bands. In the present paper, we challenge this postulate by applying a more sensitive methodology, based on Falmagne's (1976) random conjoint measurement procedure. A necessary condition for additivity of loudness was investigated in tone complexes consisting of 2...
