TED-Ed: What's that ringing in your ears? | Marc Fagelson

Tinnitus is the perception of sound without an external source, affecting many globally. It often results from internal signals generated by the central nervous system rather than external sounds.

Management strategies include sound therapy and counseling to help individuals cope with the condition.
