Q

why is the audiology diagnostic battery used?

A

because diagnosis is a complex situation and no single test is sufficient.
similar to HA verification and validation - the probe microphone is the gold standard but a battery approach is still needed

Q

what was an important finding in the marketrak viii study of the impact of the hhp on HA user success?

A

there was not a difference in outcomes between audiologists and hearing aid dispensers but that more steps in the protocol produced better satisfaction
in addition, poor satisfaction ratings with HA were associated with 4 or more patient visits to the practice
