After studying the chapter, the student should be able to . . .
|
|
|
Define sound and distinguish between its perceptual and physical qualities. Explain the properties associated with acoustic energy. |
|
|
|
Describe the nature of sound waves. |
|
|
|
Distinguish between sound intensity and frequency. Explain their units (decibels and Hertz). |
|
|
|
Identify the components of the outer ear. Explain the specific function of each and the processes by which these functions are achieved. |
|
|
|
Identify the components of the middle ear. Explain the specific function of each and the processes by which these functions are achieved. |
|
|
|
Identify the components of the inner ear, including the vestibular apparatus. Explain the specific function of each and the processes by which these functions are achieved. |
|
|
|
Describe, in detail, the complete auditory process beginning with the transmission of a sound wave through the air and ending with the stimulation of the hair cells. |
|
|
|
Contrast the two primary theories (temporal and place) of how frequencies are encoded in the inner ear. Show how place theory better accounts for the movements of the basilar membrane. |
|
|
|
Discuss how and why the cochlea generates sounds (cochlear emissions). Distinguish these sounds from tinnitus. |
|
|
|
Describe how sound stimuli activate the various neural fibers of the auditory nerve. Explain how individual fibers encode frequency and intensity. |
|
|
|
Describe the connections in the auditory pathway allowing input from the two ears to be combined. Describe the binaural cues of interaural time differences and interaural intensity differences, and explain how they could be neurally encoded. |
|
|
|
Discuss the organization of the auditory cortex and how different sounds are processed in different parts. |
|
|
|
Discuss studies of the human auditory cortex. |
