THX Certified Cinemas are quiet. They feature massive wall structures to isolate the cinema from the outside world—creating a pristine audio sanctuary. With these walls, audiences can focus on the movie experience in front of them, as opposed to distracting sounds from neighboring cinema auditoriums, outside traffic and lobby activity.
The walls in a THX Certified Cinema are constructed to provide sound isolation from other auditoriums.
Without the use of the recommended building materials, thin wall construction allows sound to pass through to neighboring auditoriums.
