APPROXIMATION OF THE LAWS OF ATTENUATION OF SOUND PRESSURE IN ZONES OF INTERFERENCE MAXIMA

Kuznetsov G.N., Stepanov А.N.

Analytic dependences determining the propagation-related laws of attenuation of the sound pressure of low-frequency signals formed in a waveguide in zones of interference maxima are obtained and investigated. As applied to the Pekeris waveguide and a non-directional monopole source, convenient approximating expressions are found that are in good agreement with the exact laws of the drop in the pressure field in these zones.
