2.11 Verification with Visible Speech Mapping

2.11.1 Considerations before you begin

Visible Speech Mapping can be run side by side with the relevant fitting software. After fitting the hearing aid,
Visible Speech Mapping can be used to verify if the client's speech area is amplified sufficiently using these
stimuli: ISTS, Male Speech, or Female Speech.
Visible Speech Mapping can be used as a verification measure and does therefore not necessarily need to
be performed together with an Insertion Gain measurement. Visible Speech Mapping provides a precise
measure of the SPL at the ear drum matched up to a fitting target selected by the clinician.
The following description provides an introduction to the clinical use of Visible Speech Mapping. The system
can be used in all sorts of ways. Clients have very different needs and this section demonstrates the options
offered by the system.

2.11.2 Visible Speech Mapping (in ear mode)

1) Open the REM440 module.
2) Select a test protocol that includes Visible Speech Mapping in the List of Protocols.
3) Explain the procedure to the client.
4) Perform otoscopic examination.
5) Mount the probe tube on the in-situ headset and place it on the client who should be seated ½-1
meters from the speaker.
Ensure that the probe tubes are calibrated before placing them in the ear canal (see section 0 about
tube calibration).
6) Carefully insert the hearing aid without moving the probe tube. Ensure that the instruments are
switched on.
7) If fitting an open hearing aid solution, perform Calibrate for open fit (see section 0).
8) Click on the Visible Speech Mapping button if it is not already marked automatically.
Note: A right click on Visible Speech Mapping button allows you to enter the Settings menu or
Change colour of the curve..
9) Check that the information about client, fitting prescription and hearing
aid to the right are correct by pressing Show fitting prescription and
test information.
