A waterproof hearing aid container. A dry hearing aid kit with a desiccant pouch (small beads that capture and stow water from hearing aids) is best, but any kind of airtight container will work.
Desiccant, in the event of rain, snow, or even high humidity, is a must. Including a small pouch in your preparedness kit will help your hearing aids to continue functioning if they become wet during the day.
Your hearing aid cleaning tools. These usually include a wax pick and a brush for cleaning dust and debris from your devices. If you find yourself without your cleaning tools in an emergency, a paper clip can be used to scrape the surface of the opening of your hearing device’s tubing, and a soft toothbrush can remove debris from the microphone. But keep in mind that you should never poke the paper clip inside the tubing, as this may damage your hearing aid.
A pen and paper. These simple communication tools can come in very handy in an emergency, for someone with profound hearing loss or deafness.
An extra pair of hearing aids, if you have them.
A spare set of batteries, or a recharging kit (don’t forget a power adaptor!).
A list of emergency contacts (friends and family), written on a piece of paper as well as programmed into your cell phone. Also include on this paper a list of city, county and state emergency numbers.
Change the battery - a dead battery is usually the cause of a dead hearing aid.
Clean your devices carefully - Using your wax pick, brush, or improvised cleaning tools, carefully clear wax, dirt and debris from the tip of the hearing aid, and for behind-the-ear models, clean the tubing. Blockages such as wax and other debris are the second most common cause of a non-functioning hearing aid.
Dehumidify them - Moisture can wreak havoc on the internal components of hearing aids, and can even cause them to suddenly stop functioning. If your devices are still not working after you have replaced the batteries and cleaned them, dry them out in a dehumidifying kit or even in a Ziploc bag with a packet of desiccant. Overnight is best, but if you need them more urgently than that, an hour or two in the drying case can help.
