Winter Care for Hearing Instruments


In the wintertime you need to take extra care of your hearing aids to protect them from the cold temperatures and the even wetter weather.

Unless youíre working outside for many hours in the freezing cold, itís highly unlikely that your hearing aids will be affected by the low temperature. The real problem is caused by the condensation which occurs when you go from building a snowman outside, to coming inside to your warm and cosy home.

Itís easier than you think to work up a sweat when youíre outdoors in the winter, especially if youíre doing something active like clearing the snow from your drive, taking part in sport or even going for a brisk walk. Unless youíve got a water-resistant hearing aid, moisture can be its worst enemy. Humidity, perspiration, condensation or accidentally dropping your hearing aid in the sink or shower can; ruin the microphone and receiver, clog the earmold tubing and sound outlet and cause corrosion.

Here are some signs your hearing aid may have been damaged by moisture:

  • Your hearing aid cuts out during loud noises.
  • Your hearing aid stops working, then suddenly begins working again.
  • Sound seems to fade, or come and go.
  • Sound is accompanied by static.
  • Sounds are unclear or distorted.

If you have any of these problems with your hearing aids, turn them off and remove the batteries. Since many of these problems can be caused by batteries which need replacing, try putting in some new ones. Remove any moisture from where the batteries touch the hearing aids with a dry cotton swab first. Check to make sure the earmold and sound outlet arenít clogged with wax and the tubing isnít frayed or cracked. If your hearing aid still doesnít work, you could try:

  • Buying a hearing aid drying kit or dehumidifier and following the directions.
  • Putting it on newspaper to air-dry for at least 24 hours.
  • Sealing your hearing aid in a plastic bag containing 190g of uncooked rice. Rice can work like a dehumidifier and soak up any water from your hearing aid.
  • Use a fan or hairdryer on its lowest setting - do not use high heat.
