6.2 Audiometry
The first step in a hearing aid fitting is to obtain the patient’s audiometric infor-
mation. These can include hearing threshold levels (HTL), bone conduction
values, uncomfortable levels (UCL), and audiometric transforms. All of these
measurements can be stored in the Audiometry window. Some values, such as
the UCL and transform values, can be predicted from the patients HTLs and age.
See Figure 6.2.
