DAI Market Forecast Through 2035: Aging and the Spread of Wireless Audio Drive Growth

The IndexBox report projects that the direct audio input (DAI) market index will rise from a 2025 baseline of 100 to 168 by 2035, representing a compound annual growth rate of 5.3%. Demand is driven mainly by a growing population with hearing loss due to aging, as well as increases in the installed base of hearing aids and cochlear implants. Bluetooth Low Energy Audio is driving DAI’s shift from physical interfaces toward integrated wireless functionality. Hearing aids account for about 62% of end-use demand for DAI.
