1
Q

how do we determine HL?

A

examining the relationship between bone and air conduction thresholds

2
Q

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

A

conductive (outer or middle ear)

3
Q

conductive hearing loss causes

A

decrease in loudness, doesn’t affect understanding

-should not exceed 60 dB, this suggest neural involvement

4
Q

air bone gap

A

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

5
Q

if there is an AB gap,

A

look at tymps to confirm this finding

6
Q

AB gaps are only found when there is..

A

conductive or mixed HL

7
Q

sensorineural HL

A
  • characterized by loss of clarity of speech
  • HL for air and bone
  • no medical interventions, unless tumor growth
  • can use amplification
8
Q

conductive HL configuration is typically

A

flat

9
Q

mixed HL

A

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

10
Q

mixed HL SOL

A

outer and/or middle AND inner

conductive portion of HL may be treated for SN will remain

ex) impacted cerumen and presbycusis

11
Q

if SRT is different than pure tone?

A

audiogram is inaccurate
