A recently developed technique known as analogue transformation acoustics has
allowed the extension of the transformational paradigm to general spacetime
transformations under which the acoustic equations are not form ...

We apply a homogenization process to the acoustic velocity potential wave equation. The study of various
examples shows that the resulting effective properties are different from those of the homogenized pressure
wave ...
