You have heard of the THX standards?
This standard which labels a multitude of Home Cinema (HC) equipment for their quality of restitution is not limited, at the base, to technical-marketing criteria.
When multi-channel systems arrived in dark rooms, countless acoustic problems came with them.
For equipment manufacturers and installers, the 2.0 system was already generating a lot of difficult to manage acoustic problems … But certain architectural solutions made it possible to transport sound where it was necessary with a sufficiently intelligible reproduction for the criteria and films of the time.
With the multi-channel system, the management of reflections and resonances has become impossible to master.
The result was very bad, and a radical and effective solution had to be found.
This is how the THX standards were born. To recreate an environment favorable to the reproduction of sound in cinemas. These standards therefore passed, above all, through an acoustically treated room.
Today, all cinemas are acoustically treated.
It is important to note also that the digital processing integrated into your electronic devices does not in any way manage the problems related to resonances, echoes, and reverberations.
Whether you have digital processing or not, passive processing in a home theater is essential!
