Researchers from the University of Auckland have developed a smartphone app called Mindear that reduced the impact of tinnitus in two-thirds of users over eight weeks.Tinnitus, often referred to as ringing in the ears, is the perception of sound without an external source and affects 10% to 15% of the global adult population. Previous studies to treat tinnitus have focused on neuromodulation devices, but a smartphone app could make treatment more accessible to a wider population.
