A time method version of the transfer matrix method

Steele, K; Hargreaves, JA

Abstract

Porous absorbers are ubiquitous in acoustics applications. They are, for example, widely used to
control reverberation in rooms and cavities, or to provide attenuation in ducts. Because of this, they
have attracted significant research effort to better understand and model their properties, typically
informed by the material’s micro-structure. However, the complexity of these models, and the fact
that many of the parameters they require are not readily measurable, means that simpler empirically fitted models are still widely used in Room Acoustics applications.
