1. An air amplifier, comprising:
air amplification engine configured to utilize energy from a high-pressure input stream of gas to accelerate a low-velocity input stream of gas to provide a high-velocity, high-volume input stream of gas; and
an air guide comprising:
a first faceplate to form an innermost assembly of the air guide that is situated within the air guide along a longitudinal axis of the air guide, the first faceplate being configured to:
shape the high-velocity, high-volume input stream of gas as the high-velocity, high-volume input stream of gas propagates through the air guide to provide a high-velocity, high-volume output stream of gas, and
allow unwanted noise generated by the high-velocity, high-volume input stream of gas to propagate through the first inner faceplate,
an active acoustic absorption chamber, situated within the air guide along the longitudinal axis of the air guide, having a plurality of acoustic suppression elements that are normal to the longitudinal axis of the air guide, the plurality of acoustic suppression elements being configured to generate a plurality of noise suppression waves that destructively combine with the unwanted noise propagating through the first faceplate, and
a second faceplate to form an outermost assembly of the air guide that is situated within the air guide along the longitudinal axis of the air guide.
