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.

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.

Records consisted of audiometric data (air and bone conduction, uncomfortable levels, speech reception thresholds speech discrimination scores, stapedius reflex and tympanometry, Tinnitus Handicap Inventory), quality of life evaluation using questionnaires (health related quality of life [15-D], Health Related Questionnaires, Charlson Comorbidity Index), HA outcome measures using questionnaires (Speech, Spatial and Qualities of Hearing scale [SSQ-12], International Outcome Inventory for Hearing Aids [IOI-HA]) and HA fitting data (HA types, log data, fitting rationale and real-ear measurements).
