6.551J Acoustics of Speech and Hearing (MIT) 6.551J Acoustics of Speech and Hearing (MIT)

Description

The Acoustics of Speech and Hearing is an H-Level graduate course that reviews the physical processes involved in the production, propagation and reception of human speech. Particular attention is paid to how the acoustics and mechanics of the speech and auditory system define what sounds we are capable of producing and what sounds we can sense. Areas of discussion include: the acoustic cues used in determining the direction of a sound source, the acoustic and mechanical mechanisms involved in speech production and the acoustic and mechanical mechanism used to transduce and analyze sounds in the ear.

HST.721 The Peripheral Auditory System (MIT) HST.721 The Peripheral Auditory System (MIT)

Description

In this course, experimental approaches to the study of hearing and deafness are presented through lectures, laboratory exercises and discussions of the primary literature on the auditory periphery. Topics include inner-ear development, functional anatomy of the inner ear, cochlear mechanics and micromechanics, mechano-electric transduction by hair cells, outer hair cells' electromotility and the cochlear amplifier, otoacoustic emissions, synaptic transmission, stimulus coding in auditory nerve responses, efferent control of cochlear function, damage and repair of hair-cell organs, and sensorineural hearing loss.

HST.722J Brain Mechanisms for Hearing and Speech (MIT) HST.722J Brain Mechanisms for Hearing and Speech (MIT)

Description

An advanced course covering anatomical, physiological, behavioral, and computational studies of the central nervous system relevant to speech and hearing. Students learn primarily by discussions of scientific papers on topics of current interest. Recent topics include cell types and neural circuits in the auditory brainstem, organization and processing in the auditory cortex, auditory reflexes and descending systems, functional imaging of the human auditory system, quantitative methods for relating neural responses to behavior, speech motor control, cortical representation of language, and auditory learning in songbirds.

HST.723J Neural Coding and Perception of Sound (MIT) HST.723J Neural Coding and Perception of Sound (MIT)

Description

This course focuses on neural structures and mechanisms mediating the detection, localization and recognition of sounds. Discussions cover how acoustic signals are coded by auditory neurons, the impact of these codes on behavioral performance, and the circuitry and cellular mechanisms underlying signal transformations. Topics include temporal coding, neural maps and feature detectors, learning and plasticity, and feedback control. General principles are conveyed by theme discussions of auditory masking, sound localization, musical pitch, speech coding, and cochlear implants.
