SHS 150 Midterm Study Guide Spring 2014
This is a tentative study guide to help you prepare for the midterm exam. It does not cover every topic that will be on the exam. It would be wise to review lecture slides, readings, lecture notes & quizzes to adequately prepare for the exam. Good luck, everyone!
Definitions:
Audiologist
Sound wave
Sound source
Medium
Intensity Frequency Wavelength Period Threshold
Hearing loss/hearing impairment Concepts:
Condensation vs. Rarefaction Constructive vs. Destructive interference of waves Physical vs. Psychophysical measures of sound Impedance vs. admittance Impedance mismatch and Impedance matching
Sound transduction
Acoustic energy Mechanical energy Hydraulic energy Electrical impulses
Otogenic development
Germ layers of embryo (no function) Action Potential
Inhibitory vs. Excitatory neural response
Main types of neurotransmitter
Temporal coding vs. frequency coding in neurons
Afferent vs. Efferent auditory pathways
Units of measure Intensity Frequency Air pressure (SPL)
Different types of hearing loss Conductive Sensorineural Mixed
Conductive vs. sensorineural mechanism
Degrees of Hearing loss
Congenital vs. Acquired Hearing loss
Anatomy & Function: Outer ear structures (Pinna, EAC)
Middle ear structures (TM, malleus, incus, stapes, Eustachian tube, tensor tympani, stampedius muscle)
Inner ear structures (semicircular canals, vestibule, saccule, utricle, oval window, IHCs, OHCs, Organ of Corti, Basilar membrane, Reisner’s membrane, Scala Vestibuli, Scala Tympani, Scala Media) Neuron/nerve cell (parts of neuron and their function) Structure of the brain (C-SLIM, areas important for speech and hearing) Function Broca’s area Wernike’s area
Evaluation: types /purposes for
Otoscopy (purpose only)
Case History (purpose only)
Puretone tests (Air conduction vs. bone conduction)
Pure tone average (PTA) Speech tests
