Sound propagation in a shallow sea is considered in the presence of a packet of intense internal waves. It is shown that horizontal refraction caused by these packets can lead to noticeable changes in the spectrum and spatial intensity distribution of a signal propagating approximately parallel to the wave fronts of internal wave packets.
