We have obtained and studied the numerical and analytical dependences determining the distance dependences of decreasing sound pressure and orthogonal projections of the vibrational velocity vector for low-frequency signals generated in a waveguide in zones of interference maxima. As applied to a Pekeris waveguide and a multidirectional monopole source, convenient approximating expressions have been found that agree well with the exact decay laws for different vector–scalar field components in these zones.
