A two-story office in Troy, Michigan had drywall walls and ceilings and vinyl plank floors throughout, smooth surfaces that reflect most of the sound that reaches them. The office wanted clearer speech and less background din in its reception area, kitchen, private offices, open office, and conference room.
In February 2026, Memtech Acoustics measured reverberation time (RT60) and speech clarity (C50) in each space with an impulse source, recording at least two microphone positions per room. Reverberation ran from 0.9 to 1.4 seconds, highest in the open office, against a target of no more than 0.8 seconds.
Memtech used a parametric model built from the measured data to size the treatment, then laid out flat, 2-inch fabric-wrapped wall and ceiling panels with an overall NRC of 1.15, room by room, in 2D drawings. Memtech supplied the panels and coordinated their installation in May 2026.
On August 27, 2026, Memtech repeated the test with the same procedure. Every space met the target: reception 0.75 seconds, open office 0.77, conference room 0.70, private offices 0.60, and kitchen 0.55.
