Sensation: Hearing Flashcards
Wavelengths are interpreted by the brain as
Frequency or Pitch
Amplitude is interpreted as
Volume
correspond to saturation or purity in light
Timbre in sound
cycles or waves per second, a measurement of frequency
Hertz (Hz)
the visible part of the ear
Pinna
short tunnel that runs from the pinna to the eardrum
Auditory Canal
snail-shaped structure of the inner ear that is filled with fluid
Cochlea
bundle of axons from the hair cells in the inner ear
Auditory Nerve
psychological experience of sound that corresponds to the frequency of the sound waves; higher frequencies are perceived as higher pitches
Pitch
theory of pitch that states that different pitches are experienced by the stimulation of hair cells in different locations on the organ of Corti
Place Theory
theory of pitch that states that pitch is related to the speed of vibrations in the basilar membrane
Frequency Theory
theory of pitch that states that frequencies from about 400 Hz to 4000 Hz cause the hair cells (auditory neurons) to fire in a volley pattern, or take turns in firing.
Volley Principle
term used to refer to difficulties in hearing
Hearing Impairment
refers to problems with the mechanics of the outer or middle ear and means that sound vibrations cannot be passed from the eardrum to the cochlea
Conduction Hearing Impairment
the problem lies either in the inner ear or in the auditory pathways and cortical areas of the brain
Nerve Hearing Impairment
