Trident by ViAcoustics is a plug-and-play application for sound-level measurement and acoustic analysis using NI hardware. It can conduct single- or multi-channel measurements for applications such as product noise emissions, sound power-level determination, field noise surveys, and transient events. You can export data into MS Excel workbooks that you can customize to meet your specific data analysis and reporting needs.

Trident has an intuitive interface that test technicians can easily learn as well as analysis capabilities powerful enough to meet the needs of acoustic engineers and consultants.

Compliant with IEC 61672 and IEC 61260 standards, Trident is used in ISO 17025-accredited corporate and government laboratories for acoustics building, product design, and end-of-line test applications. It runs on most USB, PCI, and PXI digital signal analyzer devices from National Instruments.

See the Resources tab for more information on the Certificate of Compliance to IEC and ANSI Requirements for Sound Level Meters, Weighting Filters, and Proportional Octave Band Filters.
