ChildFit

When working with very young childr e n, it is not always possible to obtain all of the information
necessary for an accura te hearing aid fitting. To that end, W idex has developed the ChildFit procedur e
which differs f rom our usual fitting procedure. Child F it g ives you a very p r ecise estimated first f itting
based on only a fe w item s of information about the child. And in addition to our new ChildFit procedure,
the Widex Baby hearin g a id has been especially designed for inf a nts and young children.

Before the fitting session

Audiometric information mus t be obtained before you f it hearing aids. For young children, this may have
been done by means of auditory brainstem au diometry (ABR), auditory steady state responses (ASSR),
or it may have been possible to meas ure a few behavioral thre s holds for the audiogram.

You can prepare for the fitting session in order to make it as short and easy for the child as possible.
Before your client arrives, you can do the following:

1. Select your client in your database, and open Compass.

2. Connect the hearing aids.

3. Select Detect connected hea r ing aid(s). Compass finds the hearing aids and displays the Online
communication window.

4. Select OK to open the Preconditions window, where you can change any of the conditions used in
connection with the fitting. For example, you may wish to change the information about the
conditions used for establishing the audiogra m in the database, or you may choose to change
the default Widex Pediatric Rationale to the Desired S ensation Level approach (DSLv5).

The ChildFit procedure

When your client arrives f or the fitting session, do the following:

1. Explain the hearing aid fitting procedure to the parent ( or older c hild).

the hearing aids, you can do this by means of the mute icons in the toolbar.

3. Place the hearin g a ids on the child’s ears, and make sure that the correct size of eartip or mold is
used.

4. If it is possible, you should perform an in-situ RECD measurement and a feedback test.
Depending on the child’s age, it may also be possi ble to obtain a Sen s og r a m.
