6.8.4 Measuring multiple envelopes
The clinician can measure up to three different Visible Speech envelopes. For
example, it may be beneficial to perform measurements of the different pro-
grams on the hearing aid.
Another example of the usefulness of multiple measurements is when using
the voice of the spouse of the patient. Have the spouse stand a few feet from
the patient when measuring Visible Speech Envelope 1. Then use [F2] to select
Visible Speech Envelope 2. (Press [F2]. Use [
∨, ∧
] to select the desired envelope.
Press [>] to complete the selection and close the pop-up menu.) Repeat the test
with the spouse standing across the room from the patient. A comparison of the
two envelopes can demonstrate to the patient and the spouse how close they
need to be to each other in order for speech to be easily audible.
When multiple envelopes have been measured, the selected envelope measure-
ments are brighter more visible than measurements of the other envelopes. To
view a different Visible Speech envelope, use [F2] to select it, or use [F3] to tem-
porarily turn off the display of the other envelopes.
