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
