摘要：
A METALLIC SOUND TRANSMITTER OR SOUND RADIATOR COMBINES THE LOW ATTENUATION OF A POLYCRYSTALLINE MATERIAL WITH THE MALLEABILITY OF A METAL. THE ATTENUATION COEFFICIENT IS SEEN TO THE DETERMINED BY SOUND SCATTERING IN POLYCRYSTALLINE METALS AS A CONSEQUENCE OF ELASTIC ANISOTROPY WHICH IN TURN IS DETERMINED BY AN ELECTRONIC PROPERTY IN AN ALLOY, SO THAT A LOW COEFFICIENT CAN BE OBTAINED BY PROVIDING ALLOYS OF PREDETERMINED COMPOSITION WHICH HAVE THE APPROPRIATE ELECTRON PER ATOM RATIO.
