how do you hear the movie at a drive in theater
Drive-in theater The screen can be as simple as a wall that is painted white, or it can be a steel truss structure with a complex finish. Originally, the movie's sound was provided by speakers on the screen and later by individual speakers hung from the window of each car, which were attached by wire. These systems were superseded by the more economical and easier to maintain method of broadcasting the soundtrack at a low output power on AM or FM radio to be picked up by a car radio. This also allows the soundtrack to be picked up in stereo by the audience on an in-car stereo system which is typically higher quality and fidelity than the simple speakers used in the old systems.
