An independent bookshop's till-point privacy fixed from a converted Georgian townhouse's original floorboards and ceiling rose -- both kept exactly as they were.

An illustrative worked example: a 9 x 5.5 x 3.8m ground-floor sales floor (about 188m3) in a converted Georgian townhouse -- painted plaster walls, original bare floorboards, a plaster ceiling with its original rose -- at roughly 1.1 seconds reverberation.

The owner wanted the ceiling rose, cornicing and original floorboards kept fully visible, so the fix came entirely from the walls and freestanding elements: about 14m2 of full-height fabric wall panels on uncovered wall sections, an upholstered bench seat near the till (about 3m2, doubling as seating and absorption right at the complaint point), and a heavy curtain at the stockroom doorway. Result: about 0.75 seconds, target range 0.7-0.8s.

A 40-desk call-centre floor fixed for distraction distance, not reverberation time -- and why that's a genuinely different measurement.

An illustrative worked example: a 22 x 14 x 3.2m open-plan call-centre floor (986m3, 40 desks). This case is framed around ISO 3382-3 distraction distance rather than a simple before/after reverberation figure -- the source material doesn't give RT numbers, and the episode correctly doesn't invent any.

Starting distraction distance covered 3-4 desk positions with no screening. Brand guidelines ruled out taller desk screens, so the fix used a like-for-like high-performance suspended ceiling tile across the full 310m2 floor, 40 low, sightline-preserving fabric dividers, and a tuned low-level sound-masking system. Result: distraction distance down to roughly one desk position, with concentration complaints back in line with the company's other sites the following quarter.
