THX Certified Cinemas construct massive wall structures to isolate the cinema from outside distracting noises. An auditorium in a THX Certified Cinema is isolated from other auditoriums by three layers:

• Large quantity of building material
• Isolating air gap
• Large quantity of building material

Why does a THX Certified Cinema take this extra construction step? To bring you an excellent entertainment experience. For example, if you are watching King Kong in one auditorium, you don’t want to hear what is going on in Pirates of the Caribbean in the auditorium next door.

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.
