determining type of hearing loss

Question 1

how do we determine HL?

Answer 1

examining the relationship between bone and air conduction thresholds

Question 2

air thresholds are outside of normal range but bone thresholds are completely within normal limits. loss is….

Answer 2

conductive (outer or middle ear)

Question 3

conductive hearing loss causes

Answer 3

decrease in loudness, doesn’t affect understanding

-should not exceed 60 dB, this suggest neural involvement

Question 4

air bone gap

Answer 4

bone should always be better but if gap between air and bone thresholds is greater than 15 dB THIS IS ABNORMAL

Question 5

if there is an AB gap,

Answer 5

look at tymps to confirm this finding

Question 6

AB gaps are only found when there is..

Answer 6

conductive or mixed HL

Question 7

sensorineural HL

Answer 7

• characterized by loss of clarity of speech
• HL for air and bone
• no medical interventions, unless tumor growth
• can use amplification

Question 8

conductive HL configuration is typically

Answer 8

flat

Question 9

mixed HL

Answer 9

-causes hearing loss for both air and bone with a gap

Question 10

mixed HL SOL

Answer 10

outer and/or middle AND inner

conductive portion of HL may be treated for SN will remain

ex) impacted cerumen and presbycusis

Question 11

if SRT is different than pure tone?

Answer 11

audiogram is inaccurate
