Hearing aids work by amplifying and processing sounds so you can hear them more easily. Itâs true that powerful sounds played directly next to your eardrum can damage your ears and your hearing (such as loud music played through headphones). However, if you have hearing loss, the volume of well-fit hearing aids wonât be loud enough to do harm. When an experienced hearing healthcare professional fits you for a hearing aid, theyâll program the device to fit your personal level of hearing loss. This means the level of amplification and sound processing will be just enough to allow you to hear as naturally as possible.
