Can a zombie hear?

Contrary to what most people think, it's not entirely certain if zombies can hear sound and react to it. While most people think this is a given, other sources give theories that instead of hearing like we do, instead zombies have a sixth sense where when they detect nearby humans they zone in never lose the target. While this is still a theory it does raise some other questions, if zombies don't hear hear like we do. Do they see and smell like we do? Some people believe that zombies have a super sense of smell that leads them to their next victim. While with a zombies sight it is also uncertain whether they see as we do, or if they even see at all. Through trial and error we can only hope to learn and succeed. Stay strong my friends, any other info is welcome!
