National Instruments offers many tools for building custom sound and vibration measurement and analysis systems. Start with the highly integrated sound and vibration platform, comprised of powerful NI LabVIEW graphical development software and cutting-edge computer-based measurement hardware, to achieve lower costs and greater performance and flexibility in your sound and vibration measurement system. The NI sound and vibration platform is ideal for audio testing; acoustic measurements; environmental noise testing; vibration analysis; noise, vibration, and harshness (NVH) measurements; noise and vibration control; machine condition monitoring; rotating machinery evaluation; and much more.

Dynamic Signal Acquisition
With NI sound and vibration measurement hardware, you have the flexibility to create a wide variety of custom automated measurement systems on industry-standard computer platforms. Systems can combine data acquisition, modular instrumentation, signal conditioning, vision, motion, and more. NI dynamic signal acquisition (DSA) devices are designed specifically for applications requiring audio, noise, and vibration measurements. They can acquire signals at sampling rates up to 204.8 kS/s with 24-bit resolution.

Multidevice Synchronization
Options are available to build systems that synchronize acquisition on up to 5,000 channels of signals, such as accelerometers and microphones. You can synchronize NI DSA devices with less than 0.1 deg phase mismatch between channels.

Sound and Vibration Analysis Software
NI sound and vibration analysis software, including the NI Sound and Vibration Measurement Suite and the NI Sound and Vibration Toolkit, provides signal processing functionality for performing audio measurements, fractional-octave analysis, frequency analysis, transient analysis, and order tracking. NI analysis software features NI Sound and Vibration Assistant interactive software for quickly acquiring, analyzing, and logging acoustic, noise, and vibration data. With a configuration-based, flexible measurement library and open-analysis capability, Sound and Vibration Assistant is designed for quick data capture through a unique software-based measurement approach to create customized applications.
