1. What is the primary purpose of a hearing aid?
A. To cure hearing loss
B. To amplify sound
C. To regenerate hair cells
D. To prevent tinnitus
Hearing aids amplify sound to assist individuals with hearing loss;
they do not cure the condition.
2. Which type of hearing loss is typically helped by hearing aids?
A. Central
B. Sensorineural
C. Retrocochlear
D. Psychogenic
Sensorineural hearing loss is the most common type that benefits
from amplification through hearing aids.
,3. What does "SRT" stand for in audiology?
A. Sound Resonance Test
B. Speech Recognition Threshold
C. Sound Range Threshold
D. Speech Reaction Time
SRT measures the lowest level at which speech can be recognized
50% of the time.
4. Which instrument is used to measure hearing thresholds?
A. Tympanometer
B. Otoscope
C. Audiometer
D. Tuning fork
An audiometer presents tones at various frequencies and intensities
to determine hearing thresholds.
5. Bone conduction testing bypasses which part of the ear?
A. Inner ear
B. Auditory nerve
C. Outer and middle ear
D. Cochlea
Bone conduction testing bypasses the outer and middle ear, directly
stimulating the cochlea.
6. What is the role of a tympanogram?
A. To assess middle ear function
B. To test hearing thresholds
C. To measure tinnitus
D. To amplify sound
Tympanometry evaluates the mobility of the tympanic membrane
and middle ear system.
, 7. Which frequency is most important for understanding speech?
A. 125 Hz
B. 250 Hz
C. 2000 Hz
D. 8000 Hz
Frequencies around 2000 Hz are crucial for speech discrimination.
8. What is recruitment?
A. Tinnitus increase
B. Abnormal loudness growth
C. Hearing loss improvement
D. Auditory fatigue
Recruitment refers to a rapid increase in perceived loudness with
small increases in intensity, often seen in sensorineural loss.
9. A client reports feedback in their hearing aid. What is the likely cause?
A. Dead battery
B. Low gain
C. Wax in the canal
D. Poor fit or seal
Feedback often occurs when sound leaks out of the ear and re-enters
the microphone.
10. What is an ear mold used for?
A. Preventing infections
B. Coupling the hearing aid to the ear
C. Blocking tinnitus
D. Measuring impedance
Ear molds deliver sound from the hearing aid into the ear and ensure
proper fit.
11. What is the first step when fitting a hearing aid?
A. Programming the device
