organizations to increase their brand awareness and facilitate conversations with the customer.
Wave propagation in solids has been widely studied and principal advances in this field have been achieved not only for the improvements of calculus methods, but also for the high progresses attained in the description of new types of materials. This book presents innovative and original research studies describing some enhancement in both directions.
Acoustics is a discipline that deals with many types of fields wave phenomena.
Originally the field of Acoustics was consecrated to the sound, that is, the study of
small pressure waves in air detected by the human ear. The scope of this field of
physics has been extended to higher and lower frequencies and to higher intensity
levels. Moreover, structural vibrations are also included in acoustics as a wave
phenomena produced by elastic waves. This book is focused on acoustic waves in
fluid media and elastic perturbations in heterogeneous media....
