Simple Explanation

A method of directing sound precisely where it's needed by digitally adjusting how each speaker in an array plays.

Concise Technical Definition

A signal processing technique that uses digital signal processing (DSP) and individual amplification to control the phase and amplitude of each speaker in a loudspeaker array, enabling control of the direction and shape of the output beam.

Layman-Friendly Analogy

Like aiming a flashlight beam without moving your hand—just by adjusting the light inside. Beam steering lets speakers “point” sound electronically.

Industry Usage Summary

Widely used in large-scale sound reinforcement systems, houses of worship, and conference centers, beam steering allows for optimized sound coverage without physically moving the speakers. It reduces unwanted reflections and increases intelligibility in acoustically challenging spaces.

Engineering Shortcut

Beam Steering = DSP-controlled sound direction without mechanical movement.

Full Technical Explanation

Beam steering refers to the use of advanced DSP (digital signal processing) and multiple power amplifiers to control the timing and amplitude of individual elements in a loudspeaker array. By adjusting the phase relationships among drivers, the system can steer the main lobe of sound up, down, or sideways, shaping the coverage area and avoiding unwanted reflections. This enables greater precision in sound reinforcement without physical re-aiming of the speakers.
