At a previous meeting of the Society [R. Lim and R. H. Hackman, J. Acoust. Soc. Am. Suppl. 187, S40 (1990)], an improved transition matrix formulation for multiple scattering calculations was suggested, capable of exact numerical results at low to moderateka. Exact results for acoustic scattering from finite linear arrays of up to ten spherical shells were presented. In the far field, comparisons with the field due to truncated infinite arrays showed remarkable agreement. Hence it is possible to approximate the acoustic far field due to moderate to large finite groups of scatterers with fast calculations involving infinite arrays. In this presentation, results for the scattering from finite and infinite linear arrays imbedded in elastic hosts will be given. Here the strong coupling, possibly due to the host's shear degrees of the freedom, causes end effects to be more important. Energy cross sections for both compressional and shear wave incidence are presented and discussed.
