Air amplifier with noise suppression

An air guide for an air amplifier, the air guide comprising:

• a first inner faceplate to form an innermost assembly of the air guide that is situated along a longitudinal axis of the air guide, the first inner faceplate having a plurality of perforations configured to allow an unwanted noise generated by a stream of gas as the stream of gas propagates through the air guide to propagate through the first inner faceplate;
• an active acoustic absorption chamber, situated 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 inner faceplate;
• and
• a second outer faceplate configured to form an outermost assembly of the air guide that is situated along the longitudinal axis of the air guide.

An air guide for an air amplifier, the air guide comprising:

• a first inner faceplate situated within a hallow cavity of the air guide along a longitudinal axis of the air guide, the first inner faceplate having a plurality of perforations configured to allow an unwanted noise generated by a stream of gas as the stream of gas propagates through the air guide to propagate through the first inner faceplate;
• a second outer faceplate situated along the longitudinal axis of the air guide;
• and
• an active acoustic absorption chamber situated within the hallow cavity of the air guide along the longitudinal axis of the air guide between the first inner faceplate and the second inner faceplate, the active acoustic absorption chamber 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 inner faceplate.
