Hearing Loss Hearing 3 — Questions and Answers
Question 1: Hearing loss is measured in which unit on an audiogram?
- Decibels (dB) (Correct answer)
- Hertz only
- Watts
- Pascals
Correct answer: Decibels (dB)
An audiogram plots the softest sounds a person can hear, measured in decibels of hearing level.
Question 2: Frequency of sound, important in hearing tests, is measured in which unit?
- Hertz (Hz) (Correct answer)
- Decibels
- Lumens
- Newtons
Correct answer: Hertz (Hz)
Frequency, or pitch, is measured in Hertz and plotted across the audiogram's horizontal axis.
Question 3: A hearing threshold of 0 to 25 dB is generally classified as which category?
- Normal hearing (Correct answer)
- Moderate loss
- Severe loss
- Profound loss
Correct answer: Normal hearing
Thresholds within roughly 0–25 dB are considered within the normal hearing range for adults.
Question 4: Which device amplifies sound for people with mild to severe hearing loss?
- Hearing aid (Correct answer)
- Cochlear implant
- Stethoscope
- Pacemaker
Correct answer: Hearing aid
Hearing aids amplify and process sound to assist people with residual hearing.
Question 5: A cochlear implant is most appropriate for which situation?
- Severe to profound sensorineural loss with little benefit from hearing aids (Correct answer)
- Mild conductive loss
- Temporary earwax blockage
- Occasional tinnitus
Correct answer: Severe to profound sensorineural loss with little benefit from hearing aids
Cochlear implants bypass damaged hair cells and directly stimulate the auditory nerve for severe-to-profound loss.
Question 6: Ringing or buzzing in the ears without an external source is called what?
- Tinnitus (Correct answer)
- Vertigo
- Otalgia
- Presbycusis
Correct answer: Tinnitus
Tinnitus is the perception of sound, such as ringing, when no external sound is present.
Question 7: Which professional is specifically trained to diagnose and manage hearing loss?
- Audiologist (Correct answer)
- Optometrist
- Dermatologist
- Cardiologist
