And if they aren't properly maintained, they can and will malfunction. A significant part of this maintenance involves daily cleaning, which varies slightly depending on the type of hearing aid you own.
Aside from regular cleaning, you should be careful not to expose your hearing aid to moisture. It's advisable to have a dry box where you can store your hearing aid while it's charging. Many dry boxes also help disinfect hearing aids while they run, as well.
It's also recommended to turn off your hearing aids when you aren't using them to help preserve your battery life and improve its longevity. If you happen to have a hearing aid that uses disposable batteries, we recommend carrying a few backup batteries in your outerwear, just in case. More importantly, change disposable batteries promptly, inspecting your battery compartment for any signs of corrosion or leakage.
Contact your audiologist immediately if you notice signs of battery acid, which usually looks like a greenish-white film. Do not continue using the device under any circumstances.
Lastly, hair products are notorious for causing hearing aids to become clogged. To avoid this, keep your hearing aid safely stowed if you intend to style your hair. Make sure you also keep the device away from sources of extreme heat.
