Brief Answer:
Tinnitus is the medical term

Detailed Answer:
There are many causes to what is referred to as TINNITUS which refers to a noise or buzzing within someone's head. I will list just a few or the more common causes:

1. Hearing Loss
2. Infections both in the brain as well as deep within the ear
3. Brain tumors
4. compression of the vestibulocochlear nerve by a mass lesion
5. Aneurysms, fistulas, arteriorvenous malformations
6. Fluid accumulations within the middle and/or inner ears
7. Side effects from medications
8. Surgical damage
9. Swelling or inflammation of the elements of the middle or inner ear as well as autoimmune processes that affect the nerve and nerve tracts associated with the inner ear.
10. Migraine headaches/Head trauma (TBI)/Ear Trauma (Explosions, Blows to the ear)/Strokes

And that's just a start. You can get much more information about specific causes for yourself or anybody you know who may have this problem by getting a thorough examination which should always include a hearing test as well appropriate laboratory and imaging studies.

In fact, there are audiology centers who are experienced at what is called a TINNITUS EXAMINATION whereby they can actually the frequency and probable location within the head from where the sound is likely emanating followed the prescription and fabrication of what is called a white noise cancellation device which can actually be inserted in the ear in order to MASK or CANCEL OUT the frequency of the noise to the point where it is no longer heard.

If you have numbness or tingling in the back of your neck then, you should be evaluated either by a neurologist, neuro-otologist, or ENT specialist for further direction and next steps to see if there is a link to that symptom and the tinnitus.

You can get a lot of very good information on this condition by consulting the XXXXXXX TINNITUS ASSOCIATION (ATA) which is a NON-PROFIT organization in the U.S. dedicated to people with tinnitus whether it is temporary, permanent, or disabling.
