O guia definitivo para tratamento acustico

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.

The trio of engineers named these bricks, “Cobogó”, for no other reason than to incorporate the first two letters of each of their last names into the name: “CO” “BO” and “GO”.

A new grazing flow liner impedance eduction test rig (FLIR) was built at the Vibration and Acoustics Laboratory of Federal University of Santa Catarina, Brazil. Measurements can be made at up to Mach 0.25 in the lined section, where and acoustic field of up to 130 dB SPL can be generated by compression drivers upstream or downstream of the test section. In this paper, the new test rig will be described, highlighting its modular design and signal acquisition/processing characteristics, including a flow speed measurement technique based on acoustic measurements.

known as 'nukege hats' (nukege being the japanese word for shedded fur), the craze makes use of old sheds by shaping and moulding them into wacky creations.
