Hearing Aid Dispensers Written Exam Questions With
Complete Solutions To Score A+
A large perforation of TM can commonly cause how many dB of loss.
30 dB
What type of loss is favorable to medical treatment.
Conductive
Carhart Notch appearing at 2 KHz. BC test is poorer than the actual sensorineural
response in the low frequencies. Caucasian middle-aged women are most at risk.
Worse for pregnant women, who can experience a rapid decrease in hearing
ability:
Otosclerosis
___ is good to find hearing loss. ___ & SRT are within 5 to 10 dB difference.
PTA
Component in input & output compression.
Feedback circuit.
This vent in a non-occluding earmold enhances high frequencies.
Parallel vent.
What is the most common earmold material that has durability & easy
modification?
Silicone 2,000
What is the major function of the earmold?
Acoustic enhancement in the ear canal.
Provides comparison between unaided & aided output.
Functional gain.
What frequency is emphasized naturally do to the large & or open vent in the SIE
or RIC hearing aids?
High frequency.
What tympanogram shows significant negative pressure & normal mobility?
Type C.
What tympanogram shows restricted TM mobility? (Otitis media)
Type B.
What tympanogram shows normal middle ear pressure but reduced mobility?
(Fixation of the ossicular chain)
Type As.
What tympanogram shows normal middle ear pressure but hypermobility?
Type Ad.
If the acoustic reflex test shows 5dB, what type of loss should be suspected?
Non-organic loss.
What type of vent effectively modifies low frequency & In non-occluding earmolds
it enhances high frequency?
Parallel vent.
