Acoustic Doors​ETS-Lindgren's SoundSecure™ Plug-in Doors are an integral component of all ETS-Lindgren's acoustic test chambers, sound isolation rooms, and audiometric booths.​
Anechoic Chamber ​​​ETS-Lindgren's Anechoic Chambers provide a precision-grade free-field environment used to measure sound source directivity, frequency response, and noise emissions from spherically radiating sound sources.<br>
Head and Torso Test Enclosure<p>​ETS-Lindgren's Head and Torso Test (HATS) Enclosure provides a free-field environment for making head and torso measurements on small devices such as cell phones and hearing aids. </p>
Hemi-Anechoic Chambers ​​​ETS-Lindgren's Hemi-Anechoic Chambers​ provide a precise free-field environment used to measure sound sources over a reflecting plane. Typical measurements include product noise testing, sound power, sound source frequency response, and sound source directivity.<br>
Predictable Field Chambers ETS-Lindgren's Predictable Field Enclosures are designed to provide acoustical and statistical energy analysis, to optimize the engineering and design requirements needed for an end-product application. 
Reverberation Chamber ​ETS-Lindgren's Acoustic Reverberation Chambers reflect sound to produce a non-directional or diffuse sound field within the chamber. They are typically used for sound absorption, transmission loss, and sound power measurements.
Small Device Test Enclosures ​ETS-Lindgren’s Small Device (SD) Test Enclosures provide a free-field environment for making survey and engineering grade measurements on small devices. ​
