Introduction
Our qualified sales engineers assist in the selection and specification of all facilities, from our unique MAPS precision anechoic chambers to certified reverberation chambers. This degree of design flexibility along with an unwavering commitment to scientific research has made Acoustic Systems a leader in the design and manufacture of acoustic test facilities.
The sales engineers at ETS-Lindgren Acoustic Systems understand the rigors of making a new testing facility operational and, in response, created our unique Turn-Key Service.
At ETS-Lindgren Acoustic Systems we are committed to the highest possible level of customer service. Our flexible designs and stringent science combine to meet both the practical and the empirical needs of the testing chamber market throughout all the phases of design, manufacture, installation and verification. |

Anechoic and Hemi-Anechoic Chambers
ETS-Lindgren's anechoic chambers have a high-performance wall panel system that provides the low-noise environment required to test today’s low-noise products. A precision-grade free-field environment is a product of the anechoic chamber's sound absorption system that consists of white melamine wedges installed on a patented clip system that provides fast wedge installation and removal. Unlike other wedge solutions, melamine wedges provide a bright and fiber-free working environment.

Predictable Field Enclosures
Predictable field enclosures provide an engineering or survey-grade sound field (dependent on enclosure size), for sound power testing. While precision-grade sound power testing requires a hemi or full anechoic chamber, a predictable field enclosure provides an economical solution for engineering or survey grade tests allowed by many standards.

Small Device Test Enclosures
Testing can be conducted using either a single microphone, or a small array of microphones. SD enclosures can also be used with vibration test equipment when required. Four sizes of SD enclosures are available to accommodate most small test objects.

Audiometric or Hearing Conservation Booths
Several standard sizes are available. Custom sizes can be manufactured for environments with special space requirements. A number of options are available to further customize your booth.

ETS-Lindgren 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. Some examples of devices that require an anechoic environment include loudspeakers, microphones, and telephones.
The 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. To approximate the sound field found in a hemi-anechoic chamber without the use of wedges, the walls and ceiling in a predictable field enclosure are manufactured with several inches of sound absorbing material.
ETS-Lindgren’s Acoustic Systems Small Device (SD) Test Enclosures provide a free-field environment for making survey and engineering grade measurements on small devices. SD test enclosures are an affordable option when precision grade testing is not required, including testing the acoustic (sound power, sound pressure) levels of automotive components, computer hard drives, fans, pumps, and small mechanical and electric assemblies.
ETS-Lindgren offers a variety of panels and complete booths for audiometric or hearing conservation testing applications.
