The aviation industry is subject to strict requirements for aircraft noise reduction. Manufacturers seek efficient solutions to optimize their aircraft cabin comfort. With the advent of urban air mobility (UAM), vertical take-off and landing (VTOL) vehicles need to propose effective solutions to aircraft noise pollution and minimize nuisances in densely populated areas. Engineering teams are challenged to efficiently troubleshoot noise issues and develop quieter aircraft design without compromising their weight and performance objectives. How can they realize substantial aircraft noise reduction? The white paper “Reduce aircraft noise” discusses several innovative techniques that help engineers optimize their aircraft acoustic designs.
Learn how to use innovative tools to achieve aircraft noise reduction without compromising performance
Engineering teams must tackle a variety of acoustic problems at different stages of aircraft design and development. Discover innovative techniques to tackle and suppress noise issues and learn when and how to employ them. The white paper “Reduce aircraft noise” addresses questions such as:
- How to meet the target noise objectives for fly-over noise according to governmental regulations
- How to facilitate in-flight operational acoustic measurements that deliver maximal insights into the acoustic behavior
- How to optimize the aircraft cabin comfort by engineering sound design
- How to quickly and accurately pinpoint the origin of irritating noises
- How to act on the root cause of acoustic problems and their transfer paths to lower sound levels
- How to select appropriate noise-damping materials and parts
Why optimizing aircraft cabin comfort matters
Cabin comfort engineering addresses two aspects: acoustic and thermal comfort. It determines how well the pilot, the crew, and the passengers feel aboard the aircraft. Interior acoustic design is an important element of comfort. Aircraft manufacturers not only aim at reducing the noise levels inside the cabin but also seek to design an environment that is acoustically pleasant to the human ear.

Optimize aircraft noise performance with efficient aeroacoustics wind tunnel testing
The airframe noises generated by the landing gear, flaps, slats, or other high-lift devices are significant contributors to aircraft acoustic emissions, especially during the approach and landing phases. To help minimize aircraft noise pollution in the vicinity of airports, engineers need to evaluate and optimize the acoustic performance of aircraft concepts and models as early as possible.
Wind tunnel tests are effective to validate prediction models before the aircraft can fly. However, they are costly and require extensive test preparation time. Simcenter supports aeroacoustics engineers by offering solutions for highly efficient aeroacoustic wind tunnel testing.
