Hearing Loss Types of Hearing Loss Test 2 — Questions and Answers
Question 1: Unilateral hearing loss means the person has hearing loss in how many ears?
- Both ears equally
- One ear only (Correct answer)
- Both ears unequally
- No ears
Correct answer: One ear only
Unilateral hearing loss refers to hearing loss in only one ear, while the other ear maintains normal or near-normal hearing.
Question 2: Which degree of hearing loss is classified as profound?
- 26–40 dB HL
- 41–55 dB HL
- 71–90 dB HL
- 91+ dB HL (Correct answer)
Correct answer: 91+ dB HL
Profound hearing loss is classified as a hearing threshold of 91 dB HL or greater, representing the most severe category.
Question 3: Noise-induced hearing loss (NIHL) primarily damages which structures?
- Eardrum
- Ossicles
- Cochlear hair cells (Correct answer)
- Auditory cortex
Correct answer: Cochlear hair cells
NIHL destroys the sensory hair cells in the cochlea, which are responsible for converting sound vibrations into electrical signals.
Question 4: What does 'bilateral' hearing loss mean?
- Hearing loss in one ear
- Hearing loss in both ears (Correct answer)
- Fluctuating hearing loss
- Progressive hearing loss
Correct answer: Hearing loss in both ears
Bilateral hearing loss affects both ears, which can impact a person's ability to localize sound and understand speech in noise.
Question 5: Ototoxic hearing loss is caused by which factor?
- Loud noise
- Aging
- Certain medications or chemicals (Correct answer)
- Ear infections
Correct answer: Certain medications or chemicals
Ototoxic hearing loss results from exposure to substances such as certain antibiotics, chemotherapy drugs, or industrial chemicals that damage the inner ear.
Question 6: Fluctuating hearing loss, where hearing ability changes over time, is most associated with which condition?
- Presbycusis
- Noise-induced hearing loss
- Ménière's disease (Correct answer)
- Otosclerosis
Correct answer: Ménière's disease
Ménière's disease is characterized by fluctuating sensorineural hearing loss, tinnitus, vertigo, and aural fullness due to excess endolymph in the inner ear.
