Cleanhearing is a hearing solutions company and the manufacturer of Sono, a medical device and multimodal system for tinnitus relief that combines tinnitus-specific electrical stimulation technology with a tailored notched music therapy. Sono’s specialised headphones and handheld controller deliver pulses of electromagnetic energy over the auditory cortex and temporal regions of the brain to target the physiological causes of tinnitus. Patients can use Sono as a standalone treatment, or connect Sono to their smartphone and the Cleanhearing app for a second, complementary tailored notched music therapy. Sono’s patented technology was developed according to scientific research into effects of pulsed electromagnetic fields and notched music on tinnitus perception and underlying tinnitus pathophysiology. It was developed by European engineers with support from leading medical colleges in the US and Japan. In 2019, Cleanhearing was a global finalist at Falling Wall Ventures competition for science startups.
