Approximately 14% of adults experience tinnitus with 2% experiencing a severe form of it. This suggests that the global burden of tinnitus is large–similar to migraine and pain–with 740 million adults globally, and perceived to be a major problem by more than 120 million people, mostly aged 65 years or older.

Normally, the cochlea's stereocilia are long hair-like structures that transduce sound into electrical signals that can be perceived by the brain. In the absence of the genetic component protein EPS8, the stereocilia are too short to function, leading to deafness. In new research, a British team show that delivery of normal EPS8 can rescue stereocilia elongation and the function of auditory hair cells in the ears of mice affected by the loss of EPS8.

Eargo had a rough second quarter with 4,455 hearing aid systems shipped versus 12,548 (-64%) and net revenues falling to $7.2MM from $22.9MM (-68%) compared to Q2 2021.
