Headphones
1. Loosen the headband and place both the left and right side of the headphones simultaneously.
Note
•
If the headphones are not placed properly, there is risk of causing the ear canal to collapse which will result in
elevated thresholds.
2. Aim the center of the headphones towards the patient's ear canals and gently place them against the ears.
3. Tighten the headband while holding the headphones in place with your thumbs.
4. Examine the placement of the headphones to make sure they are level, and properly positioned.
Insert Earphones
1. Select the largest foam eartip that will fit into the patient's ear.
If the eartip is too small the sound will leak out and the sound level will not be accurate at the eardrum.
Insert earphones have greater attenuation between ears especially at the low frequencies; this reduces the need for
masking.
2. It is best to clip the insert earphone transducers behind the child or on the back of their clothing and then fit the
foam eartip into the child's ears.
