The domestic hearing instrument market showed steady expansion in 2017 as hearing disorders increased across both developed and emerging economies. Rehabilitation centers accounted for nearly 57% of the market, while ENT departments held approximately 29%, reflecting the growing role of specialized hearing care services in patient treatment and device adoption.
Hearing loss had already become one of the most common long-term health conditions worldwide by 2017. According to the World Health Organization (WHO), around 466 million people were living with disabling hearing loss globally, including nearly 432 million adults and 34 million children. The organization also estimated that over 1.1 billion young people were at risk of hearing damage due to unsafe listening practices.
The increasing number of hearing disorder cases directly supported growth in the hearing instrument industry. Industry estimates showed that global hearing aid sales crossed 14 million units in 2017, while the worldwide hearing aid market value remained close to USD 6.8 billion. North America represented the largest regional market, followed by Europe and Asia-Pacific.
Rehabilitation Centers Became the Largest Distribution Channel
Rehabilitation centers captured nearly 57% of the domestic hearing instrument market in 2017 because patients increasingly preferred dedicated hearing care facilities for diagnosis, device fitting, speech therapy, and long-term support.
These centers offered services beyond hearing aid sales. Most facilities provided complete audiology evaluations, digital hearing aid programming, auditory rehabilitation, tinnitus management, and follow-up consultations. This helped improve hearing aid usage rates and patient satisfaction, especially among elderly patients.
The aging population significantly influenced demand. According to the United Nations, people aged 60 years and older accounted for nearly 962 million individuals globally in 2017. Since age-related hearing loss is one of the most common chronic conditions among older adults, rehabilitation centers experienced a consistent rise in patient visits.
Digital hearing aid technology also supported market growth. By 2017, more than 90% of hearing aids sold worldwide were digital devices. Features such as directional microphones, background noise reduction, Bluetooth connectivity, and rechargeable batteries increased consumer interest in advanced hearing solutions.
ENT Departments Continued to Handle Complex Cases
ENT departments represented around 29% of the market during 2017. Hospitals and ENT specialists remained important for diagnosing severe hearing conditions, infections, inner ear disorders, and sudden hearing loss cases.
Patients often visited ENT clinics before being referred to rehabilitation centers for hearing aid fitting and therapy. ENT departments also played a critical role in cochlear implant surgeries, pediatric hearing treatment, and advanced ear disease management.
Newborn hearing screening programs expanded significantly during this period. According to the U.S. Centers for Disease Control and Prevention (CDC), over 98% of babies born in the United States underwent hearing screening by 2017. Early diagnosis increased demand for pediatric hearing instruments and rehabilitation services.
Leading Companies Expanded Their Presence
The global hearing instrument industry remained highly competitive in 2017, with a small group of manufacturers controlling most market revenues.
Denmark-based Demant generated approximately DKK 13.5 billion in revenue during 2017. Its Oticon hearing aid division remained one of the strongest brands in audiology clinics and rehabilitation centers.
Sonova reported annual sales exceeding CHF 2.6 billion during fiscal year 2017/18. The company’s Phonak hearing aids gained strong demand due to wireless connectivity and speech enhancement technologies.
GN Store Nord strengthened its market position through ReSound hearing products and generated nearly DKK 12.4 billion in total revenue during 2017.
Meanwhile, Starkey continued expanding in the U.S. private hearing care market, while Cochlear Limited reported implant revenue growth supported by rising cochlear implantation procedures worldwide.
Technology Changed Consumer Preferences
Consumer demand shifted rapidly toward smaller and more connected hearing devices in 2017. Rechargeable hearing aids became increasingly popular because they reduced battery replacement costs and improved convenience for elderly users.
Wireless hearing devices capable of connecting directly with smartphones and televisions saw strong adoption across North America and Europe. Industry analysts estimated that Bluetooth-enabled hearing aid shipments grew by more than 20% during the year.
The market also benefited from rising awareness campaigns. Governments, hospitals, and hearing organizations increased public education regarding untreated hearing loss, which has been linked to depression, social isolation, reduced workplace productivity, and cognitive decline in older adults.

Long-Term Industry Outlook
The hearing instrument industry entered a stronger growth phase after 2017 due to aging populations, better healthcare access, and improvements in digital audiology technologies. WHO projections suggest that nearly 900 million people could experience disabling hearing loss by 2050.
Rehabilitation centers are expected to remain the leading service channel because patients increasingly require continuous hearing support, counseling, and personalized device adjustments rather than one-time treatment alone.
As hearing healthcare becomes more integrated with digital technology, manufacturers and healthcare providers continue investing in connected hearing devices, tele-audiology services, and early diagnosis programs to improve long-term patient outcomes.
