Hearing Aid Industry Challenges
3
main challenges
in the hearing aid market
In 2050,
25
billion people
will suffer from hearing loss
7
million people
require auditory rehabilitation
In recent years, the growing popularity of 3C products and an increase in occupational injuries have contributed to a steady rise in the number of individuals experiencing mild to moderate hearing loss. According to the World Health Organization, it is projected that by 2050, nearly 2.5 billion people will be affected by varying degrees of hearing impairment, with approximately 700 million of them requiring rehabilitation services. Nevertheless, the prohibitive cost of hearing aids has emerged as a primary barrier preventing many of these individuals from accessing this essential technology. This predicament can be attributed, in part, to three significant challenges faced by the conventional hearing aid industry:
The primary challenge: the high operating costs
The conventional sales approach for hearing aids necessitates the use of costly soundproof chambers, specialized hearing assessment equipment, and skilled audiologists. These expenses invariably contribute to the elevated prices of hearing aids.
The second challenge: the shortage of skilled professionals
With the exception of advanced countries like Europe and the United States, many regions worldwide are grappling with a significant shortage of audiologists, impacting the accessibility and quality of hearing aid fitting and services
The third challenge: the quality of hearing aids
Contemporary hearing aids continue to grapple with issues related to sound quality, latency, and performance in noisy surroundings, thereby constraining the overall auditory experience for users.
In an effort to tackle these challenges, Rehear provides state-of-the-art AI solutions aimed at lowering the expense of hearing aids, improving accessibility, and elevating the overall auditory experience.
Our advanced hearing aid chip seamlessly incorporates active noise reduction technology and a dedicated hearing test app, enabling users to perform precise hearing assessments in various environments. This breakthrough promises a significant reduction in the costs typically associated with hearing aid fittings.
