Point (ECTS )

Kursustype:   

Varighed 2½ uge i sommerperioden.

Forelæsninger og laboratorieøvelser

At give deltagerne viden om pskykoakustik og hørelsens signalbehandling. At træne deltagerne i præsentation af videnskabeligt materiale.

The auditory system. Psychophysics, Weber-Fechner's law, Stevens law. Absolute threshold and differential threshold. Loudness. Simultaneous masking, nonsimultaneous masking, central masking. Clinical audiometry, hearing loss.
Psychoacoustic measuring methods. Signal detection theory, criterion and bias. Classical methods: Békésy, constant stimuli. Adaptive methods: transformed up-down procedures, PEST, MML.
Frequency selectivity (critical bands, ERB, excitation patterns, psychoacoustic tuning curves), models of masking. Cochlear transformation, mechanical and neural transduction, models of basilar- membrane processing.
Temporal processing, modulation perception. Speech, speech production, speech perception and speech intelligibility.
Binaural and spatial hearing, localization and lateralization, HRTFs, precedence effect, models of binaural detection.
Electrical circuit of a neuron, postsynaptic and action potentials, example models of neuronal signal processing. Auditory-evoked potentials, otoacoustic emissions, physiological correlates of auditory percepts.

Kurset er en 'Summer School' der primært henvender sig til PhD studerende i forskerskolen SNAK. NB: Kurset vil ikke blive afholdt i 2006. Det vil tidligst blive afholdt i sommeren 2007, men i en modificeret form.
