We report both experimentally and theoretically that asymmetric acoustic transmission is realized by an open channel with two triangle cavities of different sizes on each side immersed in air. This exotic phenomenon stems from asymmetric multiple scatterings induced by the triangle cavities, which is different from the previous devices based on acoustic metasurfaces. In addition, the influences of the temperature and machining inaccuracies on the asymmetric transmission effect are investigated in detail, and the asymmetric acoustic transmission still exists with the excitation of the cylindrical acoustic source. Our device is very simple and easy to be realized, and opens a new way to design the devices of the asymmetric acoustic transmission, which has great potential applications in acoustic rectifiers and acoustic diodes.
