Sonova is the world’s largest manufacturer of hearing aids and other hearing devices. While hearing aids are good at amplifying sound, much of the hearing process depends on the brain’s ability to pull signal from noise, note the direction of sound and accurately process varied frequencies at high speed. Starting in 2019, Sonova began offering BrainHQ auditory exercises to its prospects and customer to improve their hearing ability, overall brain health, and satisfaction with their hearing devices.
