New microphone mountings designed to reduce flow noise by recessing the microphones and covering the cavities will also be described, and their flow noise levels compared to flush-mounting the microphones. Typical honeycomb core, perforated face-sheet liner samples were tested at different flow speeds at FLIR. Results were fed to multiple, previously validated impedance eduction codes implemented in the laboratory. Results show good agreement between different methods at all test flow speeds.

We can break up flat surfaces by hanging large objects called diffusers. The shapes chosen for diffusers are really a matter of taste and cost. Avoid concave curves, which focus sound instead of dispersing it, but otherwise pyramids, lattices, or computer designed random surfaces all work well.
