The World Health Organization pointed out in the World Hearing Report 2021 that about 1.5 billion people around the world are currently suffering from hearing impairment. According to some statistics, there are about 72 million hearing impaired people in China, among which there are about 60 million elderly people, but the market coverage of hearing aids is less than 5%. The reason for this is that at present, most of the domestic hearing aid market is monopolized by imported brands, which account for about 90% of the market share; the local hearing aid enterprises are generally small in scale, lack of independent product innovation, and the competition of homogeneity and low price is serious, which makes it difficult to meet the market demand for miniaturized, personalized and intelligent hearing aid products; moreover, at present, there are about 1.5 billion people suffering from hearing impairment worldwide. Market demand for miniaturized, personalized, intelligent hearing aid products; In addition, the current market of hearing aid products, shell materials are mostly based on UV curing materials (polymers containing vinyl), the optional relatively single, wearing comfort is low, and equipped with better performance of the metal shell (eg, titanium alloy) of the hearing aid products are temporarily monopolized by foreign brands, and the price is high.

In 2022, the State Council incorporated ear and hearing health into the "14th Five-Year Plan" for national health. At the same time, with the acceleration of the aging process of the domestic population, the popularization of hearing health education and the enhancement of the consumption level of residents, the domestic market demand for hearing aids has begun to be released in large quantities. According to statistics, the market size of China's hearing aid market was 6.86 billion yuan in 2022, with a compound annual growth rate of 8.6% from 2018 to 2022.The relevant market analysis suggests that in the next 5 to 10 years, the penetration rate of China's hearing aid market will increase significantly, with a huge market space of 500-800 billion yuan.
