Acoustic Doors
​ETS-Lindgren SoundSecure™ Plug-in Doors are an integral component of all ETS-Lindgren's test chambers, sound isolation rooms, and audiometric booths.​



​ETS-Lindgren SoundSecure Plug-in Doors are an integral component of all ETS-Lindgren's test chambers, sound isolation rooms, and audiometric booths.  SoundSecure Doors are available with excellent acoustical ratings. These plug-in doors feature a optional window in a standard location.  The plug-in assemblies bring ETS-Lindgren's sound isolation to conventional construction.

Designed for acoustical consultants, architects and engineers, ETS-Lindgren's Plug-in Door is an effective means of providing superior sound isolation in new construction and renovation projects. SoundSecure Doors are faced with 16-gauge steel; feature mortised, cam-lift butt hinges; and are sealed with magnetic gaskets at the head and jambs. 

The doors are furnished with chrome-plated die-cast zinc handles mounted on heavy duty push plates and can be hung to swing either in or out. All exposed surfaces of the door and frames are powder coated with a paintable powder coat. While ETS-Lindgren offers a standard powder coat color, we can also provide colors to match or accent existing decor or to create an additional interior design element.
