High frequency sound reduction by air shield
This paper deals with the acoustic shielding of especially high-frequency sound by jet (Air Shield). In the shear layer of the jet, sound waves incident on the jet undergo reflection and / or scattering. We investigated the performance of the air shield with two methods. One method is the experiment...
