It is so inaudible that while experiencing it, we experienced that we have experienced absolutely no sound while this opener is running.

Another thing is the protection system of safety sensors with quick-snap brackets.

Accidently, if any person or any object comes in contact while closing the door, its sensing technology will automatically reverse the door.
