A laser device, finder of range(s), and an inclinometer are used to figure a sound producing device's position adjustment(s). Laser beam(s) of the laser device and the inclinometer characterize direction(s) of sound produced by the sound producing device. The laser beam(s) can be one or more colors or patterns each characterizing the general direction of sound produced by the sound producing device. A stadium can have many speaker housings each including a speaker, the laser, range finder and the inclinometer. Each speaker housing is mounted on, and remotely adjustable with respect to, an structural member as to the general direction of sound emitted from the speaker housing into the area for stadium seating. The inclinometer's output can be rendered by a monitor seen by an audio engineer who also uses the laser beam's direction to make adjustments to the position of the speaker housing relative to its structural member. |
