Hearing Loss Types of Hearing Loss Test 1 — Questions and Answers
Question 1: Which type of hearing loss results from damage to the outer or middle ear?
- Conductive hearing loss (Correct answer)
- Sensorineural hearing loss
- Mixed hearing loss
- Central hearing loss
Correct answer: Conductive hearing loss
Conductive hearing loss occurs when sound cannot efficiently travel through the outer ear canal, eardrum, or ossicles.
Question 2: What is the most common type of permanent hearing loss?
- Conductive
- Sensorineural (Correct answer)
- Mixed
- Central
Correct answer: Sensorineural
Sensorineural hearing loss is the most common permanent type, caused by damage to the inner ear hair cells or auditory nerve.
Question 3: Which type of hearing loss involves both conductive and sensorineural components?
- Bilateral hearing loss
- Mixed hearing loss (Correct answer)
- Central hearing loss
- Unilateral hearing loss
Correct answer: Mixed hearing loss
Mixed hearing loss occurs when there is damage in both the outer/middle ear (conductive) and the inner ear or auditory nerve (sensorineural).
Question 4: Central auditory processing disorder (CAPD) primarily affects which part of the auditory system?
- The outer ear
- The middle ear
- The cochlea
- The brain's processing of sound (Correct answer)
Correct answer: The brain's processing of sound
CAPD affects how the brain processes and interprets auditory information, even when peripheral hearing may be normal.
Question 5: Sudden sensorineural hearing loss (SSHL) is defined as hearing loss of at least how many decibels over 72 hours?
- 10 dB
- 20 dB
- 30 dB (Correct answer)
- 50 dB
Correct answer: 30 dB
SSHL is clinically defined as a rapid hearing loss of 30 dB or more affecting at least three consecutive audiometric frequencies within 72 hours.
Question 6: Presbycusis refers to hearing loss associated with which primary cause?
- Noise exposure
- Aging (Correct answer)
- Ototoxic medications
- Head injury
Correct answer: Aging
Presbycusis is age-related hearing loss that occurs gradually as the auditory system deteriorates with aging.
