Abstract: Exemplary air amplifiers described herein can utilize a high-pressure stream of gas to accelerate a low-velocity stream of gas to provide a high-velocity, high-volume stream of gas. This high-velocity, high-volume stream of gas can generate unwanted noise as the high-velocity, high-volume stream of gas propagates through the air amplifier. The exemplary air amplifiers described herein can include a multi-stage noise suppression system to suppress, for example, diminish, re-tune, or even completely cancel, the unwanted noise as the high-velocity, high-volume stream of gas propagates through these exemplary air amplifiers. The multi-stage noise suppression system can include one or more absorption materials to passively suppress the unwanted noise generated by the high-velocity, high-volume stream of gas. The multi-stage noise suppression system described herein can generate one or more noise suppression waves to actively suppress the unwanted noise generated by the high-velocity, high-volume stream of gas.
