HI, thanks for using healthcare magic
The sound is likely in your ear, it is called tinnitus.
Tinnitus is the hearing of a sound when no external sound or source is present.
It can present with different types of sounds such as ringing, buzzing, hissing, roaring, clicking.
There are different possible causes, some of these are: (1) age related hearing loss
(2)infection
(3)trauma to the ear
(4)anemia
(5)meniere's disease
(6)side effect of medication
(7)mass
An ENT doctor would be able to assess and possibly determine the cause,in some persons a cause cannot be found.
If it is related to ear wax, anemia, side effect of medication or infection then treatment of these specific conditions would help.
I hope this helps, feel free to ask any other questions
