Courses and Seminars on Noise and Vibration
|
We can provide in-company training for a fuller understanding of noise and vibration measurements. Courses can be designed to match your specific needs. It is more important to correctly understand the fundamentals of noise and vibration, than to move immediately to advanced applications without adequate preparation.

Sound Quality of Products and Psychoacoustics
|
Besides objective product specifications, mechanical product sounds are increasingly used to stimulate impuls buying of consumer products. The sound of a car door closing is synonomous with perceived product quality. Systems exist for objectively evaluating psychological evaluation of product sound. Back to top. |
Practical Use of Modern Analysis Systems
|
Spectral analysis of noise and vibration leads to a better understanding of the origins of signals. A baffling array of analysis systems exist with a wide range of application possibilities. A made-to-measure training will help you get meaningful results efficiently from your old or new analysis systems and avoid pitfalls. Everything from calibration of your system to fully documented reports can be explained in clear purposeful instructions. Back to top. |
