Audio Measurement for Architects: What You Need to Know

Every material choice, room proportion, and mechanical system specification affects the acoustic environment. Exposed concrete ceilings look striking but create RT60 values of 1.5+ seconds, making open offices unusable for phone calls. Glass partition walls provide visual transparency but zero acoustic privacy. An HVAC system sized for thermal comfort but not acoustic criteria produces background noise levels that mask speech.

The good news is that addressing acoustics during design adds minimal cost. Specifying acoustic ceiling tiles instead of exposed concrete costs the same. Routing ductwork for low velocity adds no material cost. The design stage is when acoustic quality is free; the construction stage is when it becomes expensive.

RT60 determines how reverberant the space feels and directly affects speech intelligibility. Measure with SonaVyx after construction to verify the design prediction. Background noise level (NC or NR rating) determines the ambient acoustic environment. Too high and occupants cannot concentrate; too low and every conversation is overheard. STC/Rw determines acoustic privacy between spaces and is measured per ISO 16283 with SonaVyx sound insulation tool.

Parallel walls create flutter echo. Domed ceilings focus sound at specific points. Glass curtain walls reflect all acoustic energy back into the space. Open-plan offices without ceiling absorption create unbearable noise levels. Cathedral ceilings in residential spaces amplify every sound. Each of these is avoidable with basic acoustic awareness during design.

The most effective approach is to measure after construction and compare against design predictions. SonaVyx provides all the measurement tools needed: RT60 for reverberation, SPL meter for background noise, STI for speech intelligibility, and sound insulation testing for partition performance. This verification loop ensures that the acoustic intent of the design is achieved in the built environment.
