Summary

 
The paper shows that dynamic mechanical analysis results obtained for the samples of polymers could be used to calculate their acoustic properties in a wide frequency-temperature range. Knowledge of the acoustic properties allows calculation of reflection and transmission coefficients for the polymeric plates of specified thickness, including the layered ones, with arbitrary frequencies and various incidence angles of acoustic waves.
