Sound Strategy: Acoustic Design in the Modern Office

When we begin an acoustic assessment for a new project, the first conversation is always about the client's occupancy model. Who is in the space, doing what, when? A trading floor where verbal communication is essential has fundamentally different acoustic requirements from a research department where sustained concentration is the primary activity. This sounds obvious, but the number of projects we encounter where acoustic design has been specified generically — as if the space were interchangeable — suggests it is not obvious in practice.

The three mechanisms of acoustic control

Acoustic control in interior environments operates through three mechanisms: absorption (capturing sound energy within soft materials), diffusion (scattering sound waves to prevent focused reflections), and isolation (preventing transmission between spaces). Effective acoustic design deploys all three in calibrated proportion.

Absorption is the most accessible lever in furniture specification. Upholstered seating, carpet, and wall-mounted fabric panels all contribute meaningfully to reducing reverberation time — the duration that sound persists in a space after its source has stopped. High-density foam with fabric cover, as used in the Perle Acoustic Booth, achieves absorption coefficients of 0.85-0.95 across the critical speech frequency range (500Hz-4kHz).
