Practical answers from our engineers
Over many years, Prosig's engineers have written hundreds of articles on noise and vibration measurement, from the basics of sensors and sampling to advanced analysis techniques. They're a practical reference for anyone working with test data, whether or not you use Prosig systems.
Are your hammer impact results valid? Part 1: Linearity
For a linear system, the larger the force applied to a structure, the stronger the response.

Our full library of articles, tutorials and how-tos is available on the Prosig Noise and Vibration Blog.
How impact hammer testing reveals a structure's natural frequencies, damping and mode shapes, and how to get reliable results.
Why you might change the sample rate of your data, and how to do it without introducing errors such as aliasing.
What a frequency response function is, how it's measured, and how to read one to understand a structure's behaviour.
How acceleration, velocity and displacement relate to each other, with simple conversion formulas and the pitfalls to avoid.
A guide to measurement microphones: free-field, pressure and random-incidence responses, polarisation and size, and how to choose the right one.
Why window functions change the values in your spectrum, and when to apply amplitude correction or energy correction.
