Overview

National Instruments sound and vibration software provides a complete software solution for all Acoustics, Electroacoustics, Noise Vibration Harshness (NVH), and Machine Condition Monitoring applications. Based on an open analysis capability and a flexible measurement library, the NI Sound and Vibration Measurement Suite and NI Sound and Vibration Toolkit present a unique software-based measurement approach to creating customized applications.

Both software packages include the NI Sound and Vibration Assistant, interactive software for quickly acquiring, analyzing, and logging acoustic and vibration measurements. The Sound and Vibration Assistant introduces an innovative approach to configuring your measurements using intuitive drag-and-drop steps. Combining the functionality of traditional noise and vibration analysis software with the flexibility to customize and automate routines, the Sound and Vibration Assistant can help you streamline your application.
