Mastoid placement
1. Move any hair covering the mastoid out of the way and place the flat round part of the bone oscillator securely on the
boniest portion of the mastoid without any part of the transducer touching the external ear.
2. Make sure the bone oscillator is tight on the mastoid but still comfortable.
3. If you are going to perform masking with earphones, position the other end of the bone oscillator headband over the
patient's temple on the opposite side of the head so that the headband of the earphones and bone oscillator fit on
the patient's head.
Frontal bone placement
1. For frontal bone placement, place the flat round part of the bone oscillator securely on the middle of the forehead
about an inch (2.5 cm) below the hairline.
2. Make sure the bone oscillator is tight on the forehead but still comfortable.
