Hi there. Thank you for posting your question with Healthcaremagic. I will do my best to help you.

Your mother is most likely suffering from tinnitus. This is an inner-ear problem sometimes caused by a viral infection. If its accompanied by bouts of severe dizziness (vertigo) the we call it Meniere's Disease.

If this does not go away very soon then she need to see a doctor. An underlying cause should be sought and where possible, appropriate treatment given. Assure your mother that it is unlikely that there is anything serious behind her symptoms.

I hope that I have answered your questions fully and been of some help. If you have anymore questions please contact me again anytime.

Hi welcome to healthcare magic forum,
Ringing in ear called as tinnitus. But as u told sounds in ear means a hissing / ringing sound or u mean to say some kind of voice she hears. If it is hissing or ringing sounds then it is related to inner or middle ear problems and u can consult an ENT specialist . But if u mean she hears some kind of voice then u must urgently consult a psychiatrist for evaluation.
regards.
