How to reduce or prevent acoustic feedback when wearing a hearing aid

The harm caused by feedback is obvious.It prevents people from getting the amplified sound that is normally needed from the hearing aid.

Usually, if there is only a slight whistling sound, it may be due to the earplugs of the hearing aid not being tightened or the earplugs becoming hard and the closure is not strict.In this case, re-tighten the earbuds or replace them with new ones.If you still have feedback, you need to wear a special ear mold.Because the special ear mold is sampled according to the shape of the ear canal, its sealing performance is very good. The more the hearing aid is equipped with high power, the more it needs to wear the ear mold to prevent the leakage from generating feedback.

If the feedback is very powerful, you can use a digital feedback suppression hearing aid combined with the ear mold to prevent howling.The digital feedback suppression hearing aid is a digital feedback circuit hearing aid designed specifically for feedback phenomena, specifically for suppressing feedback from hearing aids.Digital feedback suppression minimizes the occurrence of feedback and works well with ear patterns to suppress feedback.It can make the hearing loss patients get the maximum hearing compensation.

Usually you will face the following problems: occlusion or “clogging” of the sound
 Your hearing aid or ear mold is the object that takes up your ear canal space.You feel that something is blocking your voice in your ear and is referring to the “occlusion effect.”Your friend or family can block your ears with your hands to experience the feeling you experience.When there is something in your ear canal, you will feel “blocked.”It usually takes a few days to get used to it.Many hearing aids or ear molds have vents or small passages that allow air to circulate inside and outside your ear.This avoids the “occlusion effect.”
 In general, adjustments to your hearing aid programming and physical options can reduce the “occlusion effect.”Everyone’s ear structure and feel are different, so if you are experiencing occlusion problems, it is important to discuss your situation with your fitter and find the best solution.
Acoustic feedback
 Feedback occurs when the amplified sound enters the hearing aid again and is amplified again.This kind of feedback is typical and sounds like a sharp, high whistle.Loudness and pitch can vary.Acoustic feedback is often inevitable with the use of hearing aids.When you open the hearing aid into the ear canal, she will give a feedback; when your clothes slip over your head; when you wear a wide-brimmed hat; when you are wearing a pillow; or when you hug others At the time of the sound feedback can happen.
 Acoustic feedback will appear when you put your hand close to your ear.For example: the sound is not too big at first, this is normal.However, if the sound feedback occurs due to head movement or normal chewing after you have worn the hearing aid correctly, this can be considered abnormal. You can ask the fitter to correct it.
