Anechoic Wind Tunnel

The anechoic wind tunnel is located in the Mechanical and Aerospace Engineering department at the University of Florida. A picture of the facility is shown above while a schematic of the wind tunnel is shown in the figure below.  The interior dimensions (from wedge tip to wedge tip) are 5:5m long by 5m wide by 2:3m high. The wedges are constructed from fiberglass enclosed by a steel mesh screen to achieve a cut-off frequency of 100 Hz. The wall panels inside the anechoic chamber are also acoustically treated to minimize the disturbances from background noise. Details of this anechoic wind tunnel can be found in Mathew et al.
