Import PTA allows audiograms exported from GNOtometrics/Madsen Aurical Plus, Interacoustics Affinity, MedRx Avant or NOAH 3 XML to be imported into HearAid. Please note that the MedRx Avant export file does not include "masked" or "no response" tags, so the imported audiogram will carry that information
