T1 Propagation of Sound in a Waveguide with an Angular Discontinuity JF International Journal of Fluid Mechanics Research JO FMR YR 1999 FD 1999-12-01 VO 26 IS 5-6 SP 758 OP 769 AB The solution of the problem of propagation of sound in a waveguide with an angular discontinuity is constructed. The dependence of the transmission of the sound wave past the angular discontinuity on the waveguide parameters is investigated. Conditions of the emission of a piston in a waveguide with an angular discontinuity are analyzed.
