1

collects sound; "shapes frequency components

outer ear

2

matches airborne acoustic signal with fluid medium of cochlea

middle ear

3

performs temporal and spectral analysis of ongoing acoustic signal

inner ear

4

onveys and further processes the singal

auditory pathway

5

interprets the signal

cerebral cortex

6

the outer ear is? (4)

-collector of sounds
-shapes frequency components of sound
-contains pinna
- contains external auditory meatus

7

The middle ear contains (4) structures:

tympanic membrane
ossicles
entry to the cochlea
the oval window

8

____ provides a major input to the proprioceptive system

vestibular mechanism

9

occurs because some mechanical problem in the external or middle ear

conductive hearing loss

10

can result from a dysfunction of the inner ear

sensorineural hearing loss

11

Mixed-

some combination of both conductive and sensorineural

12

Sensorineural-

damage to the inner ear or auditory nerve

13

Fluctuating-

comes and goes

14

Conductive-

damage to outer or middle ear, can be transitory or permanent

15

Causes of conductive hearing loss (4)

-middle ear infections
-perforation of the eardrum
-fixation of the ossicular chain
-otosclerosis

16

causes of Sensorineural hearingloss (SNHL) 4

congenital (born with)
acquired (drugs or trauma)
presbyacusis
other disease/ tinnitus

17

vibration circumvents the ear canal, eardrum and vibrates the middle ear bones. This is called ____

bone conduction

18

familiarity

19

what are 4 contributing factors to hearing loss?

noise exposure
birth defect
age
disease
ear infection
accident

20

____ is a term used to describe what happens when your brain recognizes and interprets the sounds around you

auditory processing

21

CAPD

Central Auditory Processing Disorder

22

Central Auditory processing disorder is
