A model experiment is performed to investigate a two-dimensional problem about Rayleigh waves transmitted across a trench. A precise measurement system is newly designed for this purpose. The transmission coefficients are defined of harmonic Rayleigh waves as well as Rayleigh pulses, respectively, whose variations with relative depth of trench are empirically obtained from amplitude spectra. It is shown that the coefficient of Rayleigh pulse can be easily derived also in case of a different sourcetime function and the source pressure with finite harmonic oscillation is taken as an example. Some distinct features are pointed out in common with these variations of transmission coefficients.
