The cone of silence is a well-known film gag. But Helm Shush by Luxxbox turns the trope into something more sensible. From office proper to home office, the thermoformed, dome pendant fixture for incandescent or energy-saving bulbs dampens sound anywhere it’s placed, its shape and wool-felt covering providing a noise-reduction coefficient of 0.14. “Our original spun-copper Helm light was one of our most popular releases, so we just added acoustic properties,” company founder and managing/creative director Jason Bird says. It’s available 11 or 15 inches in diameter, in more than 50 colors for the outer shell (the interior is gray), and with contrast stitching.
