Hearing brainwaves: a new way of diagnosing epilepsy

Sonification is being used to convert brain-wave signals of people living with epilepsy into sound, by a team of researchers at the University of Sydney.

Electroencephalogram, or monitoring of brain waves, is the best diagnostic tool and most common test used to diagnose epilepsy. But learning how to diagnose epilepsy is difficult, labour intensive and takes years to master.

Participants spent two hours in a training session where they learned how to audibly distinguish between seizures and some common sounds. They were asked to perform unaided audio detection of 644 hours of EEG data that contained 46 seizures.

The results showed that the participants’ accuracy in audio detection was very similar to the accuracy of visual detection. In Australia alone there are as many as 800,000 individuals living with epilepsy.
