CIM Group, which owns the Hollywood & Highland Center, has rechristened the venue the Dolby Theatre.
As part of the change, the audio-visual technology company outfitted the theater with its Dolby 3D and Dolby Atmos projection and audio systems.
Unlike Dolby Surround 7.1, which uses different audio channels, Dolby Atmos can render sounds in space by harnessing individual speakers instead of entire speaker arrays.
Dolby Atmos also adds overhead speakers, which were installed on two 50-foot-long tresses.
The theater had been known as the Kodak Theatre since it first opened in 2001.
CIM Group dropped the Kodak name ahead of the Oscars earlier this year after a bankruptcy court judge approved the early exit of Eastman Kodak Co. from a 20-year naming rights deal it signed in 1999.
The 85th annual Academy Awards are scheduled to be held at the Dolby Theatre on Feb. 24, 2013.
Besides the Oscars, the theater is home to the Cirque du Soleil production "Iris" and will host the world premiere next Monday of the Disney-Pixar film "Brave."
It will be the first feature film released using the Dolby Atmos technology.
