How does the acoustic circulator work? It goes without saying that when you happen to stand in a heavy wind and make an attempt to shout, you can barely hear your voice should the wind itself be strong enough. This is more or less the platform in which the acoustic circulator would work with. Coming in a hexagon shape, the acoustic circulator features a trio of fans that are not too different from those found on a computer.
At each end of the device, you will find ports that contain microphones. These three ports function as “acoustic waveguides,” transmitting sound from one port to another. Whenever the fans are not turned on, sound would travel normally via all three ports. Turn on the fans and direct their airflow, and you will be able to enjoy the science that lets sound travels only in the direction that the fans are turned away from.
