Support us Appeals Tinnitus Donate Fundraise Tinnitus is a persistent ringing, buzzing, or whirring sound in your ears; it can be loud or soft, pulsing or steady. It is usually caused by a fault in the auditory system; it is a symptom, not a disease in itself. There is currently no approved or effective medicine or surgery to treat tinnitus; doctors prescribe behavioural therapies that simply ‘habituate’ people to the condition. A pilot study underway at the Bionics Institute may finally offer hope of establishing a baseline for tracking the complex changes that tinnitus triggers in our brains using a brain imaging technique called functional near-infrared spectroscopy (fNIRS).
