Researchers from US and Canadian universities have confirmed that the source of tinnitus – the ringing or buzzing in your ears after hearing nerve damage – isn’t really in your ears, it’s in your brain.

McMaster Professor Larry Roberts says they have evidence the high-pitched ringing or hissing noise tinnitus sufferers hear is generated by neurons firing in the brain, not the ear.

The phantom and sometimes constant ringing in the ears affects millions of people worldwide and has a dramatic negative impact on the quality of their lives.

Roberts says tinnitus is brought on by changes in the brain that take place when someone suffers hearing loss.
