¿QUÉ ES EL CONTROL DE LA REVERBERACIÓN?

La reverberación es la persistencia del sonido una vez que la fuente ha dejado de emitirlo, de forma similar a un eco. En las salas de cine, la reverberación suele aumentar cuando el sonido se refleja en las paredes, el suelo y el techo. For example, with action films there are typically loud action sequences, immediately followed by quieter, more dialogue-driven moments. In a THX Certified Cinema with tightly controlled reverberation, the sound of explosions ends immediately and never bleeds over into the next scene. To control reverberation, THX cover the rear wall of the auditorium with thick, absorptive material which prevents the direct sound of the screen speakers from reflecting into the seating area. THX also requires the placement of absorptive materials on the sidewalls, down to the audience’s ear level which reduces sidewall reflections. WITH ACOUSTIC PANELING Acoustic paneling controls reverberation, or echo effect, in a THX Certified Cinema. SIN PANELES ACÚSTICOS: Sin paneles acústicos, el sonido rebota en las paredes e interfiere con la banda sonora de la película.
