抄録

Now available are few data of rubber vulcanizates for mechanical and acoustic uses at audiofrequencies. In this paper mechanical and acoustic properties of various pure gum stocks are measured at frequency range from 100cps to 2, 000cps by means of longitudinal wave resonance method.<br>Dynamic moduli and propagation velocities in elastomers increase slightly with increasing frequencies, and mechanical loss factors and acoustic attenuations increase more rapidly. Elastomers, here tested, are classified in three groups as follows:<br>(Group 1); IIR, NBR and Hypalon whose properties show considerable dependency on frequencies.<br>(Group 2); NR, SBR, BR and Silicone are less dependent on frequencies.<br>(Group 3); CR, EPR and polyurethane are between (Group 1) and (Group 2).
