Dependences of the Decay of Vector–Scalar Sound Fields in Zones of Interference Maxima

Abstract

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.
