摘要：
The paper addresses the propagation of waves in a pipe of small diameter compared to the sound wavelength with an insert of a waterlike material (rubber). It is shown that this structure can sustain two propagating modes, high-velocity and low-velocity. The high-velocity mode propagates at a velocity close to that of sound in water. The low-velocity mode propagates at a velocity close to that of longitudinal waves in a waterlike rod. Consideration is given to a sound muffler design which depends for its operation on the interference of the two modes.
