Selection
Resonance
Summation
Definition 2 of 239
AC: Flat to sloping
WR: Weak to excellent
ABG: Present, but not equal at all frequencies
Tympanogram: flat or abnormal shaped
Recruitment: slight or none, exceptions are common
Acoustic reflexes: absent
Tinnitus: Varies case by case
Mixed HL summary on classification

Definition 3 of 239
30 dB 1000Hz
Masker noise presented by AC/BC is:
Vent size for a moderately-severe hearing loss:
Vent size for a mild hearing loss:
Pure tone testing should begin at
,Definition 4 of 239
International Outcome Inventory for Hearing Aids
- 7 core outcome questions
-scale of 1 to 5
-Favors patients whose 1st language is not English
REIG
HHIE
IOI-HA
APHAB
Definition 5 of 239
Usually seen when there is an excess of HF Gain
-May be described as paper rustling, keys rattling, glass plates uncomfortable/unbearable.
Solutions: Reduce vent size, add a damper, active HF Potentiometer.
Repair/reprogram: Decrease the slope, reduce HF gain, add more LF gain, add an external
receiver tube, lengthen the canal of the HA.
If a patient complains of "tinniness", what is occurring? What are some solutions? How
can this be repaired/program adjusted?
If a patient complains their voice sounds like they are"in a barrel " or "echo quality", what
could be occurring?
If a patient has a mild to moderately severe HL, what type of earmold material be used?
If a patient complains that they sound like they are "in a barrel", what are some
solutions? What repair/reprogramming could be made?
