Today’s digital hearing aids use a processor that enhances the signal and delivers it to the receiver. Many modern hearing aids today come with Bluetooth connectivity and smartphone integration allowing users to stream music directly to their devices or to connect them with a TV. Their discrete size and appearance are drastically different compared to the first devices created like the Akouphone. There are even premium level hearing aids that utilize artificial intelligence which allows automatic adjustments to certain environments by logging volume control settings and program preferences for sound specific environments. No adjustment by hand is needed when you for example enter from a quite office space into a busy restaurant.
