What causes hearing aid feedback?
When sound that was meant to travel into your ear canal leaves your ear and bounces back into the hearing aid microphone, this is known as hearing aid feedback. The sound is then reamplified, resulting in your hearing aids whistling.
This feedback may occur in a variety of situations, such as when you put on and take off your hearing aids in the morning and evening, or when someone embraces you. This is typical since your hearing aids are responding to sound reflecting back from your environment.
Hearing aid feedback might also indicate that your hearing aids need to be cleaned or that anything is wrong with them. In such instance, it’s preferable to get advice from a hearing specialist.
Hearing Aid Feedback Issues: What Causes Them?
Feedback is a high-pitched shriek or squeal from an electrical equipment that may occur for a variety of causes. The most effective strategy to solve the issue is to figure out what’s causing it, which may be:
Blockages. Sound may have nowhere else to go except out the vents and joints of the device if extra ear wax is obstructing your ear canal, generating feedback. Excess wax may be readily removed by your hearing care specialist, which will cure the issue.
Awkward fit. Every few months, hearing aids must be fitted to ensure that there are no gaps between the device and the wearer’s ear. Sound picked up by the hearing aid may reverberate back into the microphone via the gap if the device is not properly fitted, resulting in a screeching sound. This might be the cause of the issue if you’ve recently dropped weight or haven’t had a fitting in a long time.
Molding is poor. Using imprints of the wearer’s ear, a hearing aid shell should be properly moulded during the initial fitting. If the device is not correctly formed, sound may bounce off the ear canal wall instead of being directed into the eardrum. By obtaining fresh impressions, relocating the device, or making other tailored modifications, your hearing professional can remedy this issue.
There are mechanical issues. If one or more pieces of a malfunctioning or faulty gadget aren’t working correctly, feedback might occur. A hole in the tubing, an electrical connection between the casing and the speaker, or another issue might be preventing the hearing aid from providing clear sound.
Excessive loudness. It’s tempting to crank up the volume on your hearing aids. Turning it up too high, on the other hand, might cause the sound to re-enter your hearing aids, resulting in whistling. Reduce the level of your hearing aids and prevent a situation where the sound becomes so loud that it causes feedback.
