Propagation velocity of a vibration velocity wave, i.e. acoustic velocity wave
In this paper the author proves that the propagation velocity of an acoustic velocity wave in the near field differs from the velocity of a pressure wave, while both differ from c_0 in d'Alambert's equation. The velocity of an acoustic velocity wave was calculated for a point source, for a...

| Summary: | In this paper the author proves that the propagation velocity of an acoustic velocity wave in the near field differs from the velocity of a pressure wave, while both differ from c_0 in d'Alambert's equation. The velocity of an acoustic velocity wave was calculated for a point source, for a cylindrical source of zero order and for a circular piston and ring in a baffle. |
