The best kind of hearing aid for treating profound hearing loss is a behind-the-ear (BTE) hearing aid. The larger case allows for a larger battery (size 675), which in turn allows for more amplification. Smaller in-the-ear (ITE) hearing aids are cosmetically pleasing, but don’t have as much power as larger models.
One problem in treating profound hearing loss is that the more you amplify the sound, the more you increase your risk of feedback. Any excess sound that is picked up by the microphone will create a feedback loop that sounds like squealing. BTE hearing aids help address this problem because they allow more separation between the microphone (where the sound is coming in) and the ear canal (where the sound is coming out). This separation helps reduce the likelihood of feedback, just like moving a microphone away from a speaker will help with feedback in a sound system.
BTE hearing aids are no more expensive than a typical hearing aid. You can get a powerful BTE to suit a variety of lifestyles and budgets. Your provider can help you understand all the available options so you can choose the hearing aid that’s right for you.
