Small Device Noise Emission Test System


The Small Device Noise Emission Test System from VIacoustics is a turnkey solution for the measurement of noise emissions of small devices typically used in computers, consumer electronics, appliances and automobiles. The system includes all hardware and software necessary (see the components tab) for the determinations of sound power levels (1/3 octave band and A-weighted), emission sound pressure levels (normalized 1/3 OB, A-weighted and high resolution FFT) and *ISO 532B loudness. The system is designed to be operated by a technician for production level testing or to be used by an engineer in the product development process.

*ISO 532:1975 Acoustics — Method for calculating loudness level


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.
