In order to investigate hearing-aid user experience, patients participating in a clinical trial from the Better hEAring Rehabilitation project, are given the opportunity to register their experiences with their new hearing aids during a two-month period between initial fitting and a follow-up session. Experiences are registered using an on-line system that allows users to report whether or not they have experienced a series of predefined sentences (user atoms) related to everyday use of hearing aids. These user atoms are presented individually, each requiring a response from the patient. As part of the clinical trial, patients are also administered aided-performance tests in a controlled sound environment. These tests are carried out prior to reporting experiences in the on-line system and after the initial fitting as well as at the two-month follow-up session. The present contribution presents the initial data collected with the on-line system with respect to uptake of the system, frequency of use, response rate, probabilities of positive experiences and progression over time. Furthermore, a comparison of the results from the aided performance test and the experiences registered in the on-line system from a cohort of 53 patients that participated in a pilot study of the clinical trial is presented. The aim of the data analysis is to investigate how hearing-aid patients use the system and to compare in-clinic aided performance measures to out-of-clinic self-reported experiences of use.
