We analyze a two cases of the acoustic trace orientation in relation to front of IS. It is shown that acoustic effects have resonant frequency dependence when internal solitons propagate along trace. It is ascertained as well, that the IS can lead to formation of "dynamic" horizontal sound channels and as result the significant temporary fluctuations of acoustic signals will be on an acoustic trace oriented along front of internal waves. The results presented in the paper can be used as basis for the remote monitoring of the characteristics of internal solitons in ocean shelf.
