In short, when you purchase hearing aids, you’re buying a highly technical device that required a great deal of research, testing, and development to produce.

According to a study conducted by AARP, “materials such as microprocessors and microphones may be about 10 percent of the final cost for some hearing aids. Research often accounts for double to triple the cost of materials.”

Digital hearing aids are akin to very small but powerful computers for your ears that are capable of distinguishing speech in the presence of noise, and suppressing that noise while amplifying speech sounds. This specifically counteracts the effects of high frequency hearing loss—one of the most common types of hearing loss—and it helps prevent feedback and whistling often associated with older styles of hearing aids.

Additionally, the cost of hearing aids reflects the services associated with maintaining the devices throughout the course of their lives, such as hearing aid testing and calibration equipment.
