The colour of acoustics, ‘Black Art’ or grey science

The misnomer that acoustics is a “black art” is one we hear too often. While there is some art in the listening and qualification of good acoustics, mostly it’s science and engineering without the slightest hint of sorcery or the occult.

Unlike other disciplines such as architecture, structure and building services, where concepts and applications are tangible or more easily defined, acoustics deals with qualities that are heard and experienced but can’t be seen, or easily imagined.

Where there are regulatory or recognised industry standards to achieve, justification is often straightforward. When our guidance pertains solely to acoustic quality, which is often the case, it’s a much harder sell, and susceptible on the VE firing line when the value is not properly appreciated.

Effective communication is key, and the mark of a good acoustic consultant is one able to convey complex and often unintuitive concepts in a way that can be understood. For the design team, this ensures they can interpret our guidance efficiently; for the client, it enables cost benefit decisions based on our advice. Misunderstanding our guidance can lead to confusion and frustration, perpetuating the “black art” misnomer.

In many areas of acoustics, there is significant uncertainty. This arises in all aspects through calculation, manufacturing and workmanship, all of which introduce risk that needs to be managed. Conveying acoustic concepts and justifying criteria can be challenging enough without adding the complexities of risk and uncertainty. As with most things in life, everyone seeks assurances, and in this endeavour, there may be a tendency towards over-engineered designs. Where the client and design team are aligned with the acoustic strategy, appreciate and accept managed risk, there are often opportunities for cost savings and added value.

Acoustics is not a black art, but there are grey areas associated with risk and uncertainty. Our role is to navigate this through science, professional judgement and practical engineering while communicating and collaborating with our design partners to meet our clients’ needs.
