Clearly, having loudspeakers twenty meters wide is not very useful.
therefore ...
to make a narrow beam of sound from a small acoustic source, we instead generate only ultrasound

Through a combination of careful mathematical analysis and engineering insight, the Audio Spotlight sound system has become the very first, and still the only, sound beam system which generates low-distortion, high quality sound in a reliable, professional package.The HoloSonic Soundmasking System consists of our Computerized Soundmasking Generator
- 1/3 Octave Equalizer Computerised Digital Signal Processor, a HoloSonic Amplifier and a 12" HoloSonic Dish System.

$3,247.00 per system

A HoloSonic Soundmasking system consists of a Soundmasking Generator - 1/3 Octave Equalizer, a HoloSonic SoundBeam, Signal Processor / Amplifier, and an HoloSonic Emitter/Transducer, 75' Plenum Cable, and Installation Drawings.

The Soundmasking signal is converted to a highly complex ultrasonic signal by the signal processor before being amplified and emitted into the air by the SoundBeam Emitter / Transducer. Since the ultrasonic energy is highly directional, it forms a virtual column of sound directly in front of the emitter, much like the light from a flashlight. All along that column of ultrasonic sound, the air is creating new sounds (the sound that we originally converted to an ultrasonic wave). Since the sound that we hear is created right in the column of ultrasonic energy, it does not spread in all directions like the sound from a conventional loudspeaker, instead it stays locked tightly inside the column of ultrasonic energy.

Create a wall of impenetrable Soundmasking around your Boardroom, Conference Center or your entire Building
without disturbing others even 1" out of the curtain of sound.
