ETS-Lindgren’s 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.
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.
