Sound Power Level Measurement System

The ViAcoustics Sound Power Level Measurement System is designed for full compliance with industry standards for sound power level determination such as ISO 3744, ISO 3745, ANSI S12.54 and ANSI S12.55. Product test codes such as ISO 7779 for information technology equipment, IEC 60704 for noise emissions for appliances and many others can be implemented using the Sound Power Level Determination System for ViAcoustics.

The Sound Power Level Measurement System is a 10 channels system for simultaneous acquisition and signal processing using our Trident multi-channel measurement application. It utilizes the National Instruments PXI expansion chassis with three (3) each PXI-4462 data acquisition devices and ten (1) each GRAS Sound and Vibration model 46AE microphone/preamps. A GRAS 42AB calibrator with traceable calibration is provided, as well as a Acculab Reference Sound Source with NVLAP accredited calibration data. Fully integrated systems include all cables, connectors, adapters, microphone holders and stands to make it a turnkey system.
