The Noise and vibration control course provides designers or constructors with tools to reduce unwanted vibrations and noises in a product. You will learn about the mechanisms behind individual sound sources and how sound waves behave within a structure and radiate outward. Additionally, you will become acquainted with human perception of sound and how customers set requirements for noise. You will be introduced to both the underlying physical principles and practical measurement techniques.
About the course Noise and vibration control
Products are subject to increasingly stringent requirements regarding noise and vibrations. There is an awareness that noise can be harmful to hearing and vibrations can be bothersome to the (immediate) surroundings. The Noise and Vibration Control course, or quiet construction, teaches you to make products quieter and less prone to vibrations in three days. This includes knowledge about material and machine behavior along with the principles of sound reduction and associated measurement techniques. The following topics are covered during the Noise and vibration control course:
- Not only determining the cause but also how to solve it correctly
- Combining theory with practice
- Practical measurement techniques for sound and vibrations
- Relevant standards in acoustics and vibrations
- Transmission of structure-borne vibrations, the use of impedance jumps, practical isolation, absorption, and reflection

Your teacher
Bert Roozen
Your customers are demanding increasingly strict requirements regarding the noise produced by your product. If you engage in discussions about noise with your clients or work in the research, development, or testing department, then this course is ideal for you. During this course, you will learn the underlying physics principles as well as the measurement techniques that will enable you to immediately apply what you've learned. This will empower you to make your current products quieter and design future products with reduced noise levels.
Discover the possibilities to organize this course incompany
If you want to train several employees in your company, it is more interesting and cheaper to organize a course at your location. Good coordination to your company-specific situation and the deployment of highly experienced teachers who have earned their spurs in practice are essential in this regard. Mikrocentrum is CEDEO accredited and guarantees the best quality.
