5.5 Preparing for Testing
5.5.1 Preparing the Patient
The patient should sit at a distance of at least 1 m from the device.
Prior to hearing threshold level measurements, the following instructions should be given.
"You will now hear a variety of tones with various loudness levels, raise your hand,
or press the response switch, as soon as you hear the tone in either ear.“
5.5.2 Placement of Headphones (for Testing with Headphones)
Eliminate any obstructions which will interfere with the placement of the earphone
cushions on the ear (i.e. hair, eyeglasses).
Ensure that the headphones are positioned correctly: red phone on the right ear, blue
phone on the left ear. Adjust the headband of the headphones so that the earphones are
positioned at the correct height (i.e. the sound output grid exactly facing the ear canal).
