If your hearing care professional recommends hearing aids, they will work with you to calibrate them to your specific hearing loss, during a process known as fitting. The basic purpose of a hearing aid is to amplify sound. But today's hearing aids can be highly customized to your specific hearing needs—amplifying the sounds you need to hear while minimizing those you don't. While they can't exactly mimic normal hearing, they work very well for people with mild to moderate hearing loss.
