Abstract

Many hearing aids are fitted with multiple programs that the user can choose between in different situations. In the H2020 EVOTION project hundreds of hearing aid users were fitted according to their audiogram with Oticon VAC rationale with four adaptive programs that differed in the noise management profile. The programs differed on how much the noise was attenuated and the threshold at which the device started to remove noise. The hearing aids also transmitted continuous data about the sound environment and the operation of the hearing aid to a dedicated app on a smartphone. The participants had a wide range of hearing losses and was recruited from amongst new and experienced hearing aid users in six different clinics in UK, Greece, and Denmark. The data from the hearing aid users was collected for up to a year to investigate relationships between clinical factors and usage patterns. The data enables a detailed investigation of the complexity of sound environments throughout the day, relation between complexity as function of time to the clinical factors including and beyond the audiogram.
