Just like any other gadget hearing aids too can suffer from glitches. In case your hearing device has stopped working altogether or has become less effective, then there are few tests to see if they can be fixed by you.
Firstly, you must ascertain whether the hearing aid is working by simply cupping it in hands and then listening for a faint whistling kind of noise. If you hear this whistling noise then your hearing aid is still working.
However, in case you fail to hear any noise then an obvious solution is to try changing the battery. This holds true even if you’ve recently purchased a new one. If you repeatedly face problems with your hearing aids, then it would be wise to buy a hearing aid battery tester.
In The Ear (ITE) and Completely In the Canal (CIC) hearing aids:
Such hearing aids face a common problem of waxing where the wax filters get blocked. In order to avoid this from happening they should be regularly cleaned using a soft tissue or cleaning brush every night. You should take care while doing this cleaning operation as few wax filters have very fine wire mesh and it can get damaged due to brush. Therefore, you should use a tissue in this case.
For a still better performance, you can change the wax filter every four to five weeks depending upon wax build up pattern in the person. Hearing aids have their own unique design of wax filters and you must see if the one you intend to buy can easily fit in your hearing aid.
You should keep hearing aids away from the moisture in some dry place. A still better way to achieve this is by purchasing a dry aid kit.
Another very common problem with such hearing aids is clogged up microphone. These microphones are found just next to battery door. You can use the brush to remove wax or dust in a gentle way.
Behind The Ear (BTE) Hearing aids:
In such hearing aids, you should check the dome before its tubing as it can get blocked due to wax. You can use soft tissue or cleaning brush to remove the wax from the dome before going to bed.
Usually, you should replace the domes every 7-9 weeks but should first confirm the size and make as it varies from model to model.
After checking the dome, you should also check the tubing if it is free from wax. If it has been blocked, then you should replace the tube.

Receiver In The Ear (RITE)
The one big difference between the receiver in the ear type hearing aid and behind the ear hearing aid is that former has its receiver just at the end of its tubing. Usually receivers are reliable but in few cases they do create problems. In case it is creating problems, it is best to get in touch with your audiologist and ask for a new receiver.
It’s quite usual for the hearing aids to have some sort of their own noise though it may vary to some extent from one make to another. However, if this noise level increases to uncomfortable levels then you must consult your audiologist.
Even after taking all the remedial measures discussed above, if your hearing aid is still not working properly, then you will have to send it to its manufacturer for necessary repairs under the warranty.
