Sound can be a tricksy beast to try to harness.

It fills the world around us, bursting from its multitudinous sources, bouncing off surfaces as echoes – a property that makes sound both incredibly useful and deeply vexing, depending on where and how its reverberations occur.

There are some circumstances where echoes can cause problems. The most obvious example is sound recording studios, but one major problem area is probably less obvious because it’s far more ubiquitous – pipes.
