According to data from the German Department of Health and research institutions, approximately 30%-40% of elderly individuals aged 60 and above experience varying degrees of hearing loss or deafness. Hearing loss is a common health issue among the elderly.
Hearing aids are small electronic devices that help individuals with hearing loss improve their hearing, significantly enhancing their quality of life. With the continuous advancement of technology, modern hearing aids are no longer just simple amplifiers but come equipped with various smart features and customization options that assist users in hearing clearly in different environments.
There are currently various types of hearing aids available on the market, including Behind-the-Ear (BTE), Completely-in-Canal (CIC), In-the-Canal (ITC), and In-the-Ear (ITE) hearing aids. Different types of hearing aids are suitable for different degrees and types of hearing impairments, so it is important to make choices based on individual circumstances and needs when selecting hearing aids.
While in the past these medical-grade devices required a prescription, now various hearing aids can be purchased over-the-counter (OTC). Some models even imitate the size, feel, and functionalities of many popular Bluetooth earbuds on the market today.
