What Are Sound and Vibration Input Modules?

Two strain and load measurement bundles with chassis and module

C Series Sound and Vibration Input Modules interface with microphones and accelerometers to acquire acoustic and vibration signals. Use these modules for audio test; machine condition monitoring; and noise, vibration, and harshness (NVH) applications.

Easily Connect to Accelerometers

C Series Sound and Vibration Input Modules and the accompanying NI software make it fast to connect microphones and accelerometers to the module and begin testing, expediting your time to first test.

Program in C, .NET, and More

C Series Sound and Vibration Input Modules work with our free NI-DAQmx driver. You can take advantage of our documentation and example programs to begin programming your sound or vibration tests in the programming language of your choosing—including LabVIEW, Python, C, or C#.NET—for flexibility.

Acquire Accelerometer Data without Programming

With C Series Sound and Vibration Input Modules, you easily can gather sound and vibration data from microphones and accelerometers. Avoid programming using FlexLogger™ application software: Spend time gathering data, not learning a new language.
