Which of the following is the correct way to clean a silicone earmold?
Answer: Wash with mild soap and warm water, then dry completely before reattaching
Silicone earmolds should be washed with mild soap and warm water and must be completely dry before reattaching to the hearing aid to prevent moisture damage.
A patient returns with a BTE hearing aid that has a cracked earhook. What is the most appropriate action?
Answer: Replace the earhook with an identical size and style
A cracked earhook can cause acoustic leakage and feedback; it should be replaced with the correct size to restore proper function.
When storing a hearing aid for an extended period, what is the recommended battery procedure?
Answer: Remove the battery and leave the battery door open
Removing the battery and leaving the door open prevents battery leakage and allows residual moisture to escape during storage.
A patient notices their hearing aid volume fluctuates intermittently. Which maintenance issue is most likely responsible?
Answer: Corroded or loose battery contacts
Intermittent volume fluctuation is a classic sign of poor electrical contact due to corroded or improperly seated battery contacts.
What does a blocked microphone port on a hearing aid most commonly cause?
Answer: Reduced sensitivity and distorted or muffled sound
A blocked microphone port prevents sound from reaching the transducer, resulting in reduced sensitivity and muffled or distorted audio.
Which of the following is a contraindication for using an ultrasonic cleaner on hearing aid components?
Answer: Any component containing electronics
Ultrasonic cleaners can destroy electronic components; only non-electronic parts such as earmolds and tubing should be placed in them.
A patient complains that their hearing aid tubing has become stiff and discolored. What should be done?
Answer: Replace the tubing, as it degrades over time and affects sound quality
Hearing aid tubing hardens and yellows with age, which reduces acoustic performance; replacement is recommended every 3–6 months.
