Document Summary

Metrical structure: how does he perceive the music"s sound as perceptually oragnized in. Auditory localization: sounds at different locations create an auditory space, locating of sound sources in auditory space. Sound frequencies patterns of nerve firing perception of a tone"s pitch & Binaural cues for sound localization: both ears, azimuth, two binaural cues. The difference between when a sound reaches the left ear and when it reaches the right ear. Jeffress: neural coincidence model, neural circuit, determine the itd (interaural time difference, the jeffress model of auditory localization, neural coincidence detector (= coincidence detector) simultaneously, itd detectors. Firing of neuron 5 itd = 0. Each tuned to respond best to a specific itd. They only fire when both signals coincide by arriving at the neuron. Itd is indicated by the place: jeffress model. Itd tuning curve of a neuron in the gerbil"s. Perception of sound: frequency, sound level, location in space, relation to other sounds.
