Underwater Acoustics Analyzer
Date: January 2003
Client: Pacific Noise and Vibration
Status: Completed, operational
Project Description: ICON Technologies worked with Pacific Noise and Vibration to develop a multi-channel system for collecting 24-bit acoustic data from underwater hydrophones.
The data acquisition unit is a National Instruments PXI Modular Instrumentation Chassis with embedded controller running LabVIEW RT software that is contained in a moored pod on the sea floor. All data are transferred over a 2 km Ethernet cable to a surface monitoring station for archival storage.
Any one of the monitored channels can be selected for replay via DirectSound to provide real-time audio feedback to the operator at the surface monitoring station.
This application was a "Best Applications Paper" finalist in the Communications Category, NI Week 2003.
