Hi Lucky
I would say that you have what is known as Tinnitus.
I and many millions have this continuous 'buzz' or 'ring'(described by sufferers). It is a complaint which has not been too well studied by the medics but there are supposed to be some possible relief actions which one can pursue. One of the most proposed aids is an earplug which emits a low noise, supposedly to mask the ringing.
I have suffered this tinnitus for 20 years and treat it as part of my life, but it is sometimes hard to mask, especially when there is no other noise to take your mind off the one in your ears!Like when reading in a quiet room or when trying to sleep during the night.
Actually, after 20 years I decided to pay a visit to my doctor just a couple of weeks ago to see if there is anything else around which could help because the sounds have been getting stronger lately. He only knew of a tablet called Betahistine which I am now trying.
But he did say that it probably won't work! and after a couple of weeks it hasn't worked for me...yet.
A lot of musicians suffer this tinnitus by virtue of having been so close to loud noises for most of their life, especially large Speakers!
I hope you are able to get rid of your problem soon.
cheers
