Hearing Aid Care

If you’re a hearing aids user, maintaining their performance is vital as you look to enjoy greater clarity on a long-term basis. Feedback (that unwanted screeching or whistling sound) is one of the most common issues reported to audiologists. Finding ways to stop those issues will aid daily activities, prevent headaches, and decelerate future damage.

Here are four methods that can prevent feedback to ensure that your hearing (and devices) in great health.

Reinsert

Perhaps the most obvious reason for potential feedback is that the hearing aid isn’t correctly inserted. This issue may leave you feeling a little silly, but you’d be amazed at how regularly this problem occurs. Any audiologist will confirm this.  

If the whistling has appeared suddenly, there’s a very good chance that taking the device out and reinserting it will solve the problem. Try pulling the earlobe down while inserting the device as this will ensure it sits properly in the ear canal.

On a separate note, adjusting the volume of the hearing aid may provide the solution to those feedback problems.  

Remove earwax

Problems with feedback aren’t always rooted in faults with the hearing aids. Inserting a device into your ear canal can naturally see it come into contact with earwax, and this can cause a few issues.

Earwax is a naturally occurring part of human life, and it actually has a huge role to play in protecting the ears. Nonetheless, a big buildup of earwax can cause blockages to the canal. In turn, this can impact the amplification provided by the hearing aids, resulting in buzzing. This whistling due to wax is something that also impacts non-wearers.

There are several ways to clear earwax, including irrigation with a syringe. However, this can be dangerous if there is a burst eardrum. Getting checked by an expert is key.

Refit

Loose-fitting hearing aids allow the noise to escape the ear canal. In turn, this can result in feedback as well as reduced hearing. Therefore, this is another issue to consider.

There are several ways to check whether this is the source of your problems. Rubbing a small amount of petroleum jelly on the device can serve as a barrier between the gaps. Meanwhile, pushing the device a little deeper (but not too far) into the canal can plug those gaps. If you notice that feedback has stopped after these steps, a loose fit is the likely issue.  

It may be necessary for the device to be re-cased or re-shaped by an expert.

Repair

Hearing aids are quite delicate items. Even if your audiologist has provided you with a robust product, there’s no doubt that it could succumb to wear and tear. Feedback is one of the most common signs that there is a fault with at least one part of the device.

It may be tempting to repair visible damages such as bent or misshaped elements yourself. Unfortunately, your untrained eye is unlikely to restore the hearing aid to its very best. Even if you do minimize the problem, it’s still there. Worse still, the deterioration will soon resume.

A professional repair job now will save you a lot of time and money in the long run. For the sake of your hearing and pocket alike, speaking to an audiologist is advised.
