Acoustic bulletin, Vol. 1 ¹ 2, (1998) p.65-72
The solution of the problem on sound propagation in the waveguide with a break is developed. The dependence of sound wave passage over the break on the waveguide parameters has been studied. The conditions of piston radiation to the waveguide with a break are analyzed.
