About Quiet Single Acoustic Phone Booth
OBJEKT's Quiet Single Phone Booth is a CE-marked free-standing acoustic enclosure for one occupant. Walls are a 50 mm composite of recycled-PET acoustic core, painted MDF outer skin and a 32 mm tempered laminated glass front door (8 + 8 mm dual-pane). Internal NRC of 0.85 is achieved with a wool-felt back wall and ceiling. A silent EC-fan with motion sensor refreshes air every 90 seconds; LED light dims via a single front-panel touch slider; an integrated USB-C, USB-A and Type-F outlet trio sits below the desktop. Floor-rolled on installation, the booth ships flat-pack in a single crate per unit and assembles by two people in 50–60 minutes with the supplied hex tools.
