Hearing aids market to hit US$15.3 billion by 2031 as AI and OTC devices spread

A large unmet need

"The hearing aids market is evolving rapidly as advances in AI, rechargeable technology, and over-the-counter devices make hearing care more accessible," said Mayur Jain, Research Expert at Wissen Research. He added that innovation and growing awareness of untreated hearing loss are expected to play a key role in shaping the industry.

The World Health Organization (WHO) estimates that more than 1.5 billion people worldwide live with hearing loss and about 430 million need rehabilitation for disabling hearing loss. The report notes the number of people with hearing disorders could reach 2.5 billion by 2050. Aging populations are expanding the pool of users, while noise at work and in leisure activities is adding younger people to it.

WHO calls untreated hearing loss a serious public health issue because it limits communication, education, work, and social life. According to the report, the gap between the number of people with hearing loss and the number who use appropriate devices is where the industry is competing.

AI platforms from three major makers

The report describes a shift from simple sound amplifiers to connected, rechargeable, AI-enabled devices. Modern hearing aids use directional microphones, feedback cancellation and adaptive noise reduction, and processing can now tell speech from background noise and adjust amplification to the acoustic setting. A crowded room remains the hardest test, and the report says results depend on factors such as device design.

In August 2026, three of the five top players the report names each introduced a new AI platform:

• Sonova launched Phonak EON, featuring real-time artificial intelligence to improve speech understanding and reduce listening effort. The smaller, lighter device is positioned in the premium segment and launches first in the United States, followed by Australia and key European markets.
• Demant A/S introduced Oticon Reveal, with Dual AI technology that processes speech and contextual sounds simultaneously in real time, plus improved feedback control and enhanced wireless connectivity.
• WS Audiology A/S introduced Signia's Multi-adaptive Xperience (MaX) platform, which integrates four deep neural networks to process speech, background noise, environmental sounds, and the wearer's own voice. It also offers rechargeable functionality and expanded Bluetooth and Auracast connectivity.

Over-the-counter sales and convenience features

The U.S. Food and Drug Administration (FDA) has defined a category of over-the-counter (OTC) hearing aids for adults over 18 with mild to moderate hearing impairment. They can be bought in a store or online without a prescription or fitting appointment. The report sees this enabling self-fitting technology, easier-to-use devices, lower-priced products and more consumer-oriented distribution. OTC devices are not right for every case, and children and people who need specialized assessment still require professional fitting.

Rechargeable batteries, Bluetooth streaming, smartphone apps, remote fitting and teleaudiology are also changing expectations, according to the report, and are especially helpful for older users.

Barriers and market structure

The report lists high costs of devices and fitting, limited coverage from public programs, low awareness, stigma and limited access to hearing specialists as factors that can slow adoption. Results vary by person, and even advanced devices can struggle in noise.

Hearing aid devices held a leading position by product type in 2025, and digital devices led by technology type. North America is the leading region, while Asia Pacific is the fastest-growing, with China, India and Japan the most important national markets. The market is moderately consolidated, with a small group of established manufacturers, while smaller and consumer-focused firms compete in specialized and price-sensitive segments.

What it means for users

For buyers, the report points to more choice in how to get a hearing aid, from clinics to online stores and OTC products where regulations allow, and to devices with better speech processing and easier daily use. Cost, access to specialists and stigma remain obstacles, and people with more complex needs still depend on professional assessment.
