Trident’s sound intensity module operates in parallel with the sound level measurement features of Trident, allowing you to acquire both sound pressure levels and sound intensity levels simultaneously. Any pair (or two pairs) of microphones can be designated as a sound intensity pair in the configuration file. Multiple channels of sound intensity may be measured simultaneously. The application also support 3D intensity probes and wide band intensity probes, such as those provided by GRAS Sound and Vibration. Acquisitions can be triggered using the probe handle controls on GRAS intensity probes.
