3.3 Listening check
Perform listening checks routinely to make sure that the equipment is functioning properly.
• Use a person who has auditory thresholds below 10 dB and make sure that he or she can hear a very faint sound for
each stimulus type, frequency and for each transducer at 0 to 5 dB.
• If the person cannot hear the stimulus, contact the manufacturer or local representative to troubleshoot the system.
• It is recommended that the system be calibrated annually or according to the local requirements.
3.4 Preparing the client
3.4.1 Hygienic precautions
It is important that hygienic precautions are taken to protect the client from cross-infection. Be sure to follow any estab-
lished infection control procedures for the setting in which you are working.
•
Headphones
Clean the headphones between patients, e.g. with a non-alcohol based antibacterial wipe, such as Audiowipes.
• Insert earphones
Warning
•
To prevent cross-infection, use new eartips when you test the next client.
3.4.2 Inspecting the client’s ear(s)
1. Position the client so that you can easily access the client’s ear(s).
2. Grasp the pinna and gently pull it back and slightly up and away from the client's head.
3. Inspect the ear canal and make sure that you can see the ear drum.
If you can see apparent narrowing of the ear canal, it may be blocked by vernix or debris, or it may not be straight.
4. If the ear canal is blocked, for instance by vernix or debris, the outcome of the procedures may be affected.
Clean the ear canal if required.
3.5 Proper transducer placement
Headphones
1. Loosen the headband and place both the left and right side of the headphones simultaneously.
