Lifestyle Prole
The Lifestyle Prole helps to identify and prioritize
listening situations for your client. If completed,
it will determine the default settings for listening
programs and features in the tting phase.

The Client’s Noah audiogram will form the basis
for the Chronos frequency response. Alternatively,
in situ audiometry may be performed at this point
by clicking on “Create in situ audiogram”.
Your client’s real ear data may also be entered to
facilitate a more customized hearing aid tting.
Client
Personal Data
Review your client’s Personal Data and hearing
instrument Experience Level for accuracy.
You will also nd a choice of tting rationales.
We recommend our BernaFit NL-1 rationale for
Chronos ttings. For maximum initial comfort for
rst time hearing aid users, you may also choose
our BernaFit Comfort rationale.
