So what makes this energy “acoustic”?

    Basically because the wave form is a longitudinal wave, just like a sound wave in the air. It's a pressure wave, only in this case, the "pressure" is exerted not on ordinary matter as such, but on the fabric or structure of space itself. It is thus a very powerful wave. In order to distinguish this wave from ordinary sound I have used various terms for it, such as "scalar wave" or "gravito-acoustic" and so on.
