hello and welcome to health care magic, You seem to have a neural hearing loss, unfortunately in this case it is impossible to get the hearing back. Though some research is happening in the stem cells, it is in a very infantile stage to even recommend that. You should go for either a four or even higher channel digital hearing aid which you can put within the ear canal without any problem. The most common reason why hearing aid does not work is that you are not using them properly and that it needs servicing. You must understand that hearing aids are not like spectacles which you can just wear and use. They are digital amplification devices which have to be fine tuned for effective and proper utilization. You must thus consult a good ENT surgeon and a good audiometrician who will guide you in this. Remember that hearing aids will be your life long companion and they should be treated in that way.
