New technology detects early signs of tinnitus using consumer headphones

Regular consumer headphones could be harnessed as a means of detecting tinnitus using new technology developed in the UK.

Created by the British engineering and design consultancy Plextek, the prototype system monitors subtle changes to auditory evoked potentials (ABR), a type of signal sent from the brain by an acoustical stimulus that measures an individual's auditory ability level.

Using a standard laptop and USB audio card, ABR waveforms were successfully recorded by incorporating this technology into standard in-ear headphones, including everyday brands such as Sennheiser and Sony.

This system has been proven to reliably detect early signs of tinnitus well before a person would become aware of the symptoms. By syncing with a smartphone app, the technology could be used to alert the wearer of the potential problem and encourage them to seek help.

Collette Johnson, director of medical and healthcare at Plextek, said: "By placing easily accessible detection technology within consumer products, everyone can constantly self-monitor and act quickly on a condition like tinnitus, which often has life-changing effects on sufferers."

Currently, one in ten people suffers from persistent tinnitus – a sensation akin to ringing in the ears – in the UK. Those spending a lot of time in loud environments, military settings or music venues are at greater risk of developing the condition.
