Design and demonstration of an acoustic right-angle bend

J Acoust Soc Am. 2017 Jul;142(1):84. doi: 10.1121/1.4990952.

Abstract

In this paper, a broadband acoustic right-angle bend device in air is designed, fabricated and experimentally characterized. Perforated panels with various hole-sizes are used to construct the bend structure. Both the simulated and experimental results verify that the acoustic beam can be rotated effectively through the acoustic bend in a wide frequency range. This model may have potential applications in some areas such as sound absorption and acoustic detection in elbow pipes.
