Hearing aids are technological tools, and just like computers or smartphones, there might be occasions when they stop working correctly. Many of these situations are easily fixable, such as a low battery. Every hearing aid runs on a battery. Most hearing aid batteries will last days, but this will depend on the features you’re using on a daily basis. Even rechargeable batteries eventually need to be replaced. A low battery can cause issues such as poor sound quality, weak sounds, and hearing aids that won’t turn on. In other cases, your hearing aids may have to be cleaned. Dirty hearing aids can cause feedback, muffled sounds, and even discomfort. A regular cleaning routine and yearly professional cleanings can get your hearing aids back to normal.
