Wind Tunnels

Anechoic Wind Tunnel

The anechoic wind tunnel comprises a electric fan that passes through an inlet silencer and discharges into an anechoic chamber. The walls of the chamber are lined with acoustic foam wedges and provides anechoic conditions above 250 Hz. The resulting flow that discharges into the chamber has low turbulence intensity.

The instrumentation installed in the anechoic wind tunnel includes

  • Hot wire anemometry
  • A variety of acoustic point measurement techniques
  • Two perpendicular 31 microphone planar beamforming arrays
  • Highly accurate automated traverse system
