There are systems such as these available, with their primary use intended for motorsports such as rallying where the driver and co-driver need to be able to communicate clearly while wearing crash helmets in cars that are exceptionally noisy. These tend to be radio or Bluetooth based systems, but can be expensive. A more affordable solution may be to obtain a pair of Bluetooth ear pieces designed for hands-free phonecalls, so you can simply call your passenger before starting your journey.
