Cat. No. 351 Stereo Demonstration Film: “listen . . .”
“listen . . .”, an eight-minute Dolby Stereo demonstration film for public
exhibition, has been professionally produced to demonstrate the
commitment of the theatre to providing its audiences with the best in
both sound and picture. It is intended for screening prior to a feature
and is a fast-paced, entertaining short which shows off a quality
projection system to its best advantage. Thus, it serves to promote the
experience which only the motion picture theatre can provide and
which cannot be matched by home entertainment media.
“listen . . .” has no narration and no sales or technical message except
that implied by the quality of its presentation in the theatre. It consists
of a wide variety of short scenes, both live action and an animation
sequence, integrated into a unique sight and sound experience which
bears repeated viewing. Because there were none of the plot constraints
of a conventional feature, scenes were chosen specifically to demonstrate
different aspects of stereo sound— from a trickling brook to a cannon
salute, from a string quartet to a church organ, from the sounds of
children at play to the thundering lift-off of a Saturn 5 rocket.
To ensure quality at least equivalent to the feature likely to follow it in
the theatre, Dolby Laboratories engaged professional film craftsmen,
including several Academy Award winners, to produce “listen . . .”.

while the Cat. No.151 is used to set the level of the surround speakers
relative to the screen speakers. The Cat. No.566 is used to measure the
