摘要
The thermal transport process plays an important role in the sound attenuation in inhomogeneous media. This problem is best exemplified by the sound attenuation in a one-dimensional space with periodically alternating media. Using the transfer matrix technique, we give here a general theory of the sound propagation and attenuation in such a periodic system. © 1990, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
