Tunable sound packages consisting of granular aerogels and fibrous media
In this study, two granular aerogel materials, both consisting of particles with sizes on the
scale of 1 to 50 mm, were first investigated both theoretically and experimentally to improve …

A general and stable approach to modeling and coupling multilayered acoustical systems with various types of layers
In this article, a general method is proposed to model layered acoustical systems with two-by-
two transfer matrices, and further, to solve for their acoustic absorption, reflection, and …
