Thanks for your query.
Most commonly, cold and nasal allergies can give rise to tinnitus
(sound in the ear). It occurs because of blockage of the tube that connects the nose to the ear. If you have a cold then you can use decongestant nose drops like otrivin
nasal drops to open the tube. Once the cold settles your tinnitus will go away.
Considering your age I feel the tinnitus can be because the nerve carrying impulses from your ear to the brain is slowly becoming weak. In very early nerve deafness, there may just be tinnitus. You should consult an ENT specialist
to come to the diagnosis. If nerve deafness is suspected then you will need a test called audiometry
which is nothing but a hearing test. It will tell us if there is any nerve weakness and if present the degree of weakness.
Hope it helps.
