If excess ear wax is blocking your ear canal, sound may have nowhere else to go but out the vents and joins of the device, causing feedback. Your hearing care provider can easily solve this problem by removing excess wax. Improper fit. If a device does not fit tightly, sound that is picked up by the hearing aid may echo back into the microphone through the gap, resulting in a squealing sound. Poor molding. If the device is improperly molded, the device may be positioned so that sound bounces off the wall of the ear canal instead of being directed toward the eardrum.
Your hearing provider can solve this problem by taking new impressions, repositioning the device, or making other personalized adjustments. Like earmolds, tubes can also deteriorate over time and require replacement. The tube might shrivel up or split, causing unpleasant feedback. A visit to your HCP can solve this easily. Turning up the volume on your hearing aids can force sound back into them, causing feedback issues and whistling.
Simply turn down your hearing aid to avoid this and avoid turning it up beyond a certain point. If you're having trouble hearing, speak to your hearing care professional about solutions for that problem.
Wearing hats, scarves, and other head coverings can change the feedback path of your hearing aids. This can result in the infamous whistle or a series of annoying beeps and sound interference. To avoid this, remove your scarf or hat. Turning down the volume on your hearing aid can also help with this issue. Giving people hugs can also result in short beeps or whistles. Like hats or scarves, the person's body is changing the feedback path to your hearing aid. While these unpleasant side-effects are an inescapable part of many hearing aids, it shouldn't affect your experience too much.
Start by ensuring your devices remain free from obstructions — including hats, scarves, earmuffs, etc. This has the potential to trap sound from the receiver and cause it to re-enter the microphone, creating a feedback loop. On a day-to-day basis, keep the tip of the hearing aid or earmold secure inside your ear.
Also, if you have a volume control, we recommended to leave it as close to default as possible. Finally, remember to always have your ears checked regularly for impacted wax, which could inadvertently be damaging the hearing aids and producing that whistling noise you find so aggravating.
