Hearing test - ASSR (auditory steady-state evoked potentials)

• During the examination, silence is required, the examinee cannot chew or swallow, and has his eyes closed to reduce visual stimuli.
• In young children, the examination is usually performed after feeding, while the child is asleep:
  1) In the nighttime hours or early in the morning before the examination (before the traditional hour of getting up), it is necessary to wake the child and not allow him/her to fall asleep again until arriving at the laboratory so that at the hour of examination the child is sleepy and tired.
  Take care that the child does not fall asleep during the journey!
  2) The child should be lightly hungry on arrival at the examination, e.g. the child eats the last meal in the evening and then only in the morning at the laboratory before falling asleep.
  Feeding the child just before the examination increases the child's chances of falling asleep faster.
• The child presenting for the ASSR examination should be healthy. It is not recommended to perform the ASSR examination during an infection, due to the possibility of falsification of the results by secretions lingering in the nasopharynx. If the child has undergone an infection, it is safest to report for an ASSR test about 2 weeks after the end of the infection.

ASSR is an electrophysiological, safe and objective test. Steady-state auditory evoked potentials are the response of the hearing organ that is produced by stimulating the ear with an acoustic stimulus. The test allows assessment of the hearing threshold of both ears simultaneously.
