An estimated 21.6 million people in the US used hearing aids in 2022. In low and middle income countries, coverage for those who could benefit is only about 3%. This article examines the market size, adoption barriers, and the measurable performance gains of hearing aid technology.
Key Takeaways
- About 1.6 billion people worldwide live with hearing loss (disabling hearing loss of 250 million and moderate to severe of ~1.3 billion), establishing the total addressable population for hearing aids and related services
- In 2022, there were 21.6 million hearing aid users in the United States (estimated)
- In low- and middle-income countries, the coverage of hearing aids for people who could benefit is about 3% (system-level adoption constraint)
- A 2022 systematic review found a global mean hearing-aid adoption (among those who could benefit) of roughly 15% in high-income settings and ~3% in low/middle-income settings
- In a 2020 study, 67% of participants reported difficulty paying for hearing aids as a barrier to adoption
- In 2023, the FDA granted De Novo classification for an over-the-counter hearing aid category device; the OTC hearing aid pathway enables faster adoption for eligible devices
- As of 2022, the FDA approved/cleared multiple OTC hearing aid models under the over-the-counter hearing aid rules (OTC expansion)
- In 2021, the U.S. FDA finalized the OTC hearing aids rule establishing a new category for devices for adults with perceived mild to moderate hearing loss
- Typical speech recognition improvement with properly fitted hearing aids: 10–20 percentage-point gains in word recognition measures in clinical studies (reported range)
- In a randomized controlled trial (2020), hearing aid use improved quality of life scores by a clinically meaningful amount on validated questionnaires
- In a 2019 meta-analysis, hearing aids improved speech understanding in noise by an average standardized effect size (Hedges g reported)
- The Centers for Medicare & Medicaid Services (CMS) provides that Medicare does not cover hearing aids in most cases, contributing to out-of-pocket burden
- In Germany, statutory health insurance covers hearing aids with patient co-payments depending on device and income; average co-pays are reported around hundreds of euros (survey-based)
- In a 2019 study, hearing aid costs were a significant predictor of discontinuation, with higher costs associated with lower continuation probability
With 1.6 billion affected worldwide, low adoption persists from cost barriers, while OTC and teleaudiology expand access.

Interpretation
Market Size Interpretation
With about 1.6 billion people worldwide living with hearing loss and roughly 21.6 million hearing aid users in the United States in 2022, the market size for hearing aids is vast globally yet indicates a large opportunity for expanded adoption beyond today’s user base.

04
In 2020, about 2.8 million hearing aids were fitted in the U.K. NHS hearing services program (reported)
Interpretation
User Adoption Interpretation
User adoption remains low and is most constrained by cost, with only about 3% of people who could benefit in low and middle-income countries getting hearing aids compared with roughly 15% in high-income settings and 67% of users in one 2020 study citing difficulty paying as a barrier.

03
In 2021, the U.S. FDA finalized the OTC hearing aids rule establishing a new category for devices for adults with perceived mild to moderate hearing loss
04
In 2022, the European Union Medical Device Regulation (MDR) was fully applicable for hearing aids, affecting certification timelines and market entry requirements
05
In 2021, 55% of audiologists reported they were at least somewhat familiar with teleaudiology/remote hearing aid fitting
06
In 2020, average hearing-aid telehealth utilization increased significantly during COVID-19, with audiology clinics reporting higher remote follow-up rates
07
In 2023, the FDA required labeling on OTC devices to include warnings and indications for over-the-counter use
08
In 2022, open-fit technology accounted for 35% of global hearing aid shipments (market mix estimate)
09
In 2021, conductive wireless accessories (Bluetooth/audio streaming) were included in many modern hearing aids; a 2021 consumer survey reported 48% willingness to pay for streaming
Interpretation
Industry Trends Interpretation
With the FDA expanding the over-the-counter hearing aid pathway and finalizing the rule for adults with perceived mild to moderate hearing loss in 2021, including new De Novo classifications in 2023 and multiple OTC models cleared by 2022, the industry is clearly accelerating toward more accessible devices while teleaudiology familiarity and use have also surged, with 55% of audiologists reporting they were at least somewhat familiar with remote fitting in 2021 and much higher telehealth uptake during COVID-19 in 2020.
