I recently heard a CBC program explaining the many advancements to hearing aids. Not only have they become quite fashionable (think blue, pink, orange colours), but the technological flexibility for aid users have also taken giant steps.
I can certainly recall my Grandfather constantly trying to adjust his hearing aid between large family gathering in halls to smaller household chats. His hearing aid never seemed to find a balance that worked and most of the time was pulled out and tucked into his shirt pocket.
One advancement that relates to your car is that some digital hearing aids come equipped with the ability to utilize Bluetooth technology. Wearers can receive sound from accessories that allow them to pair with cell phones, MP3 players, and yes, their vehicles.
Driver’s with hearing aids can listen to their radio, music, podcasts and use hands-free phone with Bluetooth-enabled hearing instruments. Sounds great!
