Hearing Loss Types of Hearing Loss Test 3 — Questions and Answers
Question 1: Which audiometric pattern is most typical of high-frequency sensorineural hearing loss?
- Flat audiogram
- Rising audiogram
- Sloping downward audiogram (Correct answer)
- Cookie-bite audiogram
Correct answer: Sloping downward audiogram
High-frequency sensorineural hearing loss typically shows a sloping downward pattern on an audiogram, with worse thresholds at higher frequencies.
Question 2: Congenital hearing loss refers to hearing loss that is present at which time?
- Adolescence
- After age 65
- Birth or shortly after (Correct answer)
- Due to noise exposure
Correct answer: Birth or shortly after
Congenital hearing loss is present at or shortly after birth and can be caused by genetic factors, infections during pregnancy, or birth complications.
Question 3: Which condition is characterized by abnormal bone growth in the middle ear causing conductive hearing loss?
- Otosclerosis (Correct answer)
- Otitis media
- Ménière's disease
- Acoustic neuroma
Correct answer: Otosclerosis
Otosclerosis is an abnormal bone remodeling disorder that typically affects the stapes, causing it to become fixed and unable to transmit sound properly.
Question 4: Auditory neuropathy spectrum disorder (ANSD) is characterized by which finding?
- Normal otoacoustic emissions but absent ABR (Correct answer)
- Absent otoacoustic emissions and absent ABR
- Absent otoacoustic emissions but normal ABR
- Normal otoacoustic emissions and normal ABR
Correct answer: Normal otoacoustic emissions but absent ABR
ANSD typically presents with present (or previously present) OAEs indicating normal outer hair cell function, but absent or abnormal ABR indicating disrupted neural transmission.
Question 5: A 'cookie-bite' audiogram pattern shows greatest hearing loss at which frequencies?
- Low frequencies only
- High frequencies only
- Mid-range frequencies (Correct answer)
- All frequencies equally
Correct answer: Mid-range frequencies
A cookie-bite audiogram shows a U-shaped pattern with greatest hearing loss in the mid-range frequencies (1000–2000 Hz) and relatively better hearing at low and high extremes.
Question 6: Acquired hearing loss differs from congenital hearing loss in that it occurs:
- Only in children
- After birth, at any age (Correct answer)
- Only from genetic causes
- Only from noise exposure
Correct answer: After birth, at any age
Acquired hearing loss develops after birth and can occur at any age due to factors such as noise exposure, illness, medications, or aging.
