  • ETS-Lindgrens Small Device (SD) Test Enclosures is an acoustic chamber which provides a free-field environment for making survey and engineering grade measurements on small devices. Small device test enclosures are an affordable option when precision grade testing is not required, including acoustic testing for (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.

    Controlled Test Environment

    The SD Series isolates and controls acoustic energy to provide the ideal testing environment of small electronics, computer equipment, hearing aids and automotive components.

    Survey/Engineering Grade Design

    With minimum 10.2 cm (4 in) thick acoustic walls and sound absorbing floor and ceiling, the SD Test Enclosures are ideal for making survey and engineering level measurements on small devices.

    Applicable Test Standards

    SD Series Test Enclosures meet ISO 3746, ISO 532B, ISO 11201, GM W7293, and additional test standards.
