Who we are
We are a dedicated group of partners and people, who come from clinics, academia, technological service, and industry. We are medical audiologists and otologists, engineers, consultants and hearing aids professionals, some are young, others more experienced. Some of us work full-time on the project, others part-time juggling other obligations. A few of us know the challenges of hearing impairment first hand.

The abbreviated version of the Speech, Spatial, and Quality of Hearing questionnaire and the International Outcome Inventory for Hearing Aids were used as the self-reported HA outcome. Result: Out of 690 participants, 442 (64%) got accustomed to HAs within 2 months. Ninety-one participants (13%) did not get accustomed to the HAs at all, out of which 74 (81%) were first-time HA users.

Method: The study is a multicentre, prospective, open, non-randomized, single-arm trial with sequential enrolment of all qualified patients, conducted under a common clinical investigation plan. Up to almost 2,000 evaluable patients have been enrolled from two Danish clinics. After having undergone medical and audiological examination and other assessments (health related and quality of life questionnaires), the patients were prescribed a hearing aid and got a fitting. Approximately 2 months later, a follow-up visit took place and whenever needed an adjustment was offered (plus other assessments).

Results: The investigation generated approximately 30’000 patient records and we started by characterizing the general distribution of audiometric data (air and bone conductions, speech tests) and questionnaires (health, speech, hearing aids, tinnitus and quality of life related).
