Purpose The purpose of this study was to analyze data from the EuroTrak surveys performed from 2009 to 2015 in Germany, France, and the United Kingdom to identify factors that could account for the growth in hearing aid sales over that period.

Method Data of 132,028 people—approximately 15,000 for each of the 3 countries at 3-year intervals—were collected using a questionnaire. The sample in each country was weighted using the respective country age–gender populations to get balanced results. Furthermore, 11,867 persons with self-reported hearing impairment filled in a comprehensive questionnaire on hearing status and related matters; 4,631 were hearing aid owners. Data were pooled over the 3 countries for each of the years 2009, 2012, and 2015 and analyzed for developments over the 6-year period. In certain cases, data were pooled across countries and years. The analysis focused on hearing loss prevalence, hearing aid adoption rates, satisfaction with hearing aids, and benefits of hearing aid use.

Results Hearing loss prevalence was stable over the period around 10%—slightly higher for men than for women. Hearing aid adoption overall increased from 33% to 37%, and bilateral use increased from 55% to 69%. Intervals between hearing aid renewals decreased. These factors contribute to increased hearing aid sales. Bilateral users are more satisfied with the hearing aid product features (76%) and performance (72%) and use their hearing aids 9.1 hr per day, compared with unilateral users where the corresponding numbers are 71%, 67%, and 7.8 hr, respectively. Satisfaction with hearing aid product features and performance in general is slightly increasing; hearing aid users are 14.5% less exhausted at the end of the day compared with nonusers with similar hearing loss and exhibit less depressive and forgetfulness symptoms.

Conclusions The prevalence of self-reported hearing loss is 10.6% and stable, and hearing aid adoption has increased, particularly of bilateral fittings that are more satisfactory and exhibit higher daily use patterns. Higher uptake of hearing aids contributes to growing hearing aid sales.
