While whistling used to be a real concern for hearing aid users in the past, today’s devices feature automatic feedback cancellation technology. That means you can enjoy the outdoors on a breezy day, get out on the dance floor, and enjoy the atmosphere of a busy restaurant without the worry of your devices whistling or squealing. If your hearing aids are whistling, there may be a problem with how the sound is being transmitted through your ear canal. Talk to your provider about this problem. They will be able to make adjustments to help.
