Questions and Answers
A patient reports difficulty hearing after using cotton swabs and suspects a conductive hearing loss. Which of the following is the most likely cause based on their actions?
A patient reports difficulty hearing after using cotton swabs and suspects a conductive hearing loss. Which of the following is the most likely cause based on their actions?
- Fluid accumulation in the inner ear affecting the balance and hearing.
- Neural pathway damage affecting transmission of auditory signals to the brain.
- A plug of wax blocking the ear canal, preventing sound from reaching the eardrum. (correct)
- Damage to the hair cells within the cochlea due to prolonged loud noise exposure.
A patient's audiogram shows normal hearing at low frequencies but a significant loss at higher frequencies (e.g., 4000-8000 Hz). Which type of hearing loss is most likely, and what is the probable cause?
A patient's audiogram shows normal hearing at low frequencies but a significant loss at higher frequencies (e.g., 4000-8000 Hz). Which type of hearing loss is most likely, and what is the probable cause?
- Central auditory processing disorder affecting speech comprehension.
- Sensorineural hearing loss, possibly from noise-induced damage to hair cells. (correct)
- Conductive hearing loss due to fluid in the middle ear.
- Mixed hearing loss from eardrum perforation and nerve damage.
An audiogram reveals a patient requires a 60 dB increase in sound intensity to perceive a tone at 500 Hz. Based on this finding, how would you classify the severity of their hearing loss at that frequency?

Study Notes
Conduction Hearing Loss
- Affects the passage of sound between the eardrum and the inner ear
- Can occur due to a plug of wax blocking the eardrum
- Can occur due to a hole in the eardrum
- Can occur due to fluid in the middle ear
Nerve Hearing Loss
- Also known as sensorineural hearing loss
- Caused by damage to the hair cells in the cochlea (sensory hearing organ)
- Can be caused by damage to the neural pathways of hearing (nerves)
Hearing Test (Audiometer)
- An electronic instrument called an Audiometer is used for hearing tests
- Measures hearing across different pitches (Hz) and loudness (dB)
Levels of Hearing Loss
- Normal Hearing: -10 to 20 dB
- Mild Hearing Loss: 20 to 40 dB
- Moderate Hearing Loss: 40 to 55 dB
- Moderately Severe Hearing Loss: 55 to 70 dB
- Severe Hearing Loss: 70 to 90 dB
- Loudness: 80 to 100 dB
- Profound Hearing Loss: 90+ dB
