Abstract
A theoretical study is performed on the sound field generated by a rotating point monopole in a jet flow, the mixing layer of which is simulated by a velocity discontinuity. Its sound in the far field is compared to the sound field generated by a rotating monopole in a uniform flow in the absence of a velocity discontinuity, which makes it possible to estimate the size of the sound refraction effect.

The second equation in (9) should read:
$$\begin{array}{*{20}c} {\tilde p_m = \left[ {C_m + \frac{{i\pi }} {2}Q_m H_m^{(1)} \left( {\Gamma _2 r_0 } \right)} \right]J_m (\Gamma _2 r)} \\ { + \left[ {D_m - \frac{{i\pi }} {2}Q_m J_m \left( {\Gamma _2 r_0 } \right)} \right]H_m^{(1)} \left( {\Gamma _2 r} \right),} \\ {r_0 \leqslant r \leqslant R_0 .} \\ \end{array}$$01 March 2018
