Critical Band: How Your Brain Filters Sound
Introduction to the Critical Band Concept The critical band (CB) represents one of the most fundamental concepts in the field of psychoacoustics, serving as a cornerstone for our understanding of how the human auditory system processes complex sounds. Initially proposed by Harvey Fletcher in the 1940s, the concept describes the functional bandwidth of the “internal […]
Periodicity Theory: How Your Brain Decodes Sound
Introduction to Periodicity Theory The Periodicity Theory represents a foundational concept within the field of auditory neuroscience and perception, specifically addressing the mechanism by which the brain encodes and interprets the sensation of pitch. This theory posits a crucial departure from earlier models, suggesting that pitch is not solely determined by the physical location of […]
Phase Locking: How Our Brains Sync to Sound
Defining the Phenomenon of Phase Locking Phase locking represents a fundamental and critical physiological mechanism observed within the nervous system, particularly pronounced in the auditory pathway, describing the propensity for a neuron, specifically an auditory nerve fiber, to generate an action potential at a precise and consistent temporal relationship relative to the phase of an […]
