Diagnosis, Evaluation And Prevention Of Noise Induced Deafness

Which of the following is not a cause of sensorineural hearing loss?

• Noise-induced hearing loss

• Age-related hearing loss

• Acoustic neuroma

• Cholesteatoma

When conducting the clinic daily listening check, which 2 of the following are true?

• Deviation from previous audiogram should be equal to or less than 5dB, when using the same audiometer

• Deviation from previous audiogram should be equal to or less than 10dB, when using the same audiometer

• Deviation from previous audiogram should be equal to or less than 5 dB, when using a different audiometer

• Deviation from previous audiogram should be equal to or less than 10dB, when using a different audiometer

Which of the following may not require an ENT referral?

• Hearing loss requiring aiding (>40db at the worse hearing ear)

• Asymmetrical SNHL (> 15db in 3 consecutive frequencies)

• Abnormal ear examination findings (Infections, perforations requiring closure, cholesteatomas)

• Early Noise-induced Hearing Loss

Which of the following is the most accurate interpretation of this audiogram of a 50-year-old worker?

• Moderate to severe conductive hearing loss at mid to high frequency in both ears

• Sensorineural hearing loss only at high frequencies in both ears

• Moderate to severe sensorineural hearing loss at most frequencies in both ears

• Moderate to severe mixed hearing loss at all frequencies in both ears

Select all the audiograms suggestive of noise-induced deafness, assuming sufficient years of noise exposure.
