To achieve THX certification, the cinema projection booth must be accurately placed in relation to the screen for the best viewing experience.

The placement of the cinema screen is precisely calculated for every THX Certified Cinema. To ensure the best possible viewing experience, THX recommends having a 36 degree viewing angle from the farthest seat in the auditorium.

Reverberation is the presence of sound after its source has stopped – much like an echo. In a movie theater, reverberation often builds as sound reflects off surfaces such as walls, floors and ceilings.

THX Certified Cinemas are quiet. They feature massive wall structures to isolate the cinema from the outside world—creating a pristine audio sanctuary.

Unique to every THX Certified Cinema is the THX “baffle wall.” If you were to peel away the screen at any THX Certified Cinema, you will see a massive wall of speakers housed in an acoustic baffle (speaker system enclosure).

THX defines standards for cinema acoustics, background noise, sound isolation and image quality—promising every seat in the house is a good one.

THX offers on-site digital cinema installation and integration services to ensure a smooth transition from film-based to digital cinema systems.

The TASA standard’s intent is to equalize the sound volume of theatrical trailers so that they come close to matching the volume of the features that they precede.
