Learn how to apply cutting-edge knowledge of aeroacoustics in a simple and effective way. After taking this course you will be able to reliably measure noise in a variety of mechanical systems and develop noise reduction strategies to improve their aerodynamic design and performance.
Over the last few years, the field of aeroacoustics has developed rapidly in finding solutions for reducing noise from aircraft, engines, ventilation systems and wind turbines. However, finding the right balance between achieving maximum performance (of mechanical systems such as airplanes, cars, drones, etc.) and lowering their noise output to comply with noise regulations, and ensure people's comfort and health, is a complicated task.
Many companies are nowadays asking for combined aeroacoustic and aerodynamic knowledge and for many engineers it can be difficult to translate complex aeroacoustic theories into practical design applications. In this course, you will acquire the latest knowledge and tools that you need to work within this challenging and continuously evolving field, including aerodynamic design guidelines to maintain or improve machine performance.
You will evaluate how to measure sound and review principles in order to utilize calculations to estimate the sound generated by a variety of mechanical systems. You will develop noise reduction strategies using simulations to understand how to improve the aeroacoustics of potential designs.
Apply this knowledge to your own work
After learning the fundamentals of the aeroacoustic sources of noise, you will apply the knowledge gained to practical and industry‑relevant exercises. During the course, you will learn how to change the aerodynamic performance of the mechanical system of your choice (an aircraft propeller, a wind turbine, a wing with flap and/or a jet in the proximity of a wing) to obtain the required aeroacoustic performance. Additionally, we will explore the basics of aeroacoustic scaling and testing, in order to give you practical design guidelines that you could use in the future.
This course includes special lectures given by leading companies, including Siemens, GRAS Microphones and National Instruments which will cover industrial applications and reference to the requirements of current regulations. You will also gain access to online simulation tools and resources to tailor your formulations to your test cases, and you will receive personalized advice and feedback from international experts in the field of aeroacoustics.
After taking this course you will be able to:
- Analyze various aerodynamic mechanisms that generate noise
- Estimate, analyze and evaluate the sources of noise in different types of mechanical systems
- Evaluate the aerodynamic and aeroacoustic EU regulations in a mechanical system
