Small Device Test Chambers


SD with microphonesSmall Device Test Chambers are used for

>Basic sound level measurement of small products and equipment
>Pre-compliance testing of small products and equipment
>End of line manufacturing test on small products and equipment

Small Device Test Chambers provide acoustic isolation from outside sounds and/or reduce the sounds from the device under test radiating into the host space. They also provide sound absorptive interior environment to minimize acoustic reflections that will affect the measured sound pressure levels

Small Device Test Chambers available in several standard sizes and can be instrumented with acoustic measurements systems for single microphone sound level measurement or multiple microphone sound power level estimation.  Custom measurement applications and end of line testing applications are also implemented in the Small Device Test Chambers.


Small Device Test Systems from VIacoustics use Small Device Test Chamber from ETS-Lindgren to provide sound isolation of exterior sounds from interfering with the measurement of the sound emissions of your device.

Small Device Test Chambers provide up to 50 dB of sound isolation at frequencies above 1,000 Hz and at least 20 dB of isolation down to 100 Hz.

The amount of sound isolation you will need will depend on:

  • The sound pressure levels in the host environment in which the Small Device Test System will be installed.  This should be known in octave bands from 100 Hz up to 8000 Hz.
  • The sound pressure levels emitted by your device.  Again, this should be known in at least octave band frequency resolution from 100 Hz to 8000 Hz
  • The criteria for the noise emissions from your product

VIacoustics supplies Small Device Test Chambers from ETS-Lindgren as part of its standard and custom test systems for product noise emission measurement.

Small Device Test Chambers are available in four standard sizes that address most small device measurement applications.
