How to Know If a Movie Is Surround Sound
- 1). Ask the manager at a movie theater whether the film is presented in surround sound. The audio equipment must be activated in the projection booth to produce the sounds recorded on the film's soundtrack.
- 2). Check the bottom of the movie's lobby poster for the words "Dolby Digital® and Surround Sound."
- 3). Look at the back of the case for a movie on DVD or Blu-Ray to check the audio specifications. Movies will typically be listed as recorded in "Dolby Digital 5.1 Surround Sound." Dolby is a recording laboratory that specializes in digital audio. The company's recording technologies are the reference standard for movie soundtracks.
- 4). Watch the beginning of a movie broadcast on TV to check for the "Presented in Dolby Surround Sound" designation.
- 5). Listen. A movie played with surround sound will have instantly recognizable audio characteristics. The sound effects from the rear speakers will be different from the front left and right speakers. Dialog will come mainly from the center channel.
