Aircraft noise reduction technology

Engineering teams must tackle a variety of acoustic problems at different stages of aircraft design and development. Discover innovative aircraft noise reduction technology and techniques to help tackle and suppress noise issues – and learn when and how to deploy them.

Aircraft noise certification

Standards for aircraft noise certification are evolving. Regulation is becoming more stringent to ensure the latest available noise reduction technology is incorporated into aircraft design to reduce the environmental impact. Read this white paper for details.

Cabin comfort engineering is also a major consideration in aircraft development. 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.

Efficient aircraft noise operational measurements

Operation measurements to troubleshoot noise issues or assess the efficiency of noise control measures should be carefully planned and executed, since flight testing typically involves high costs. For example, it is important to use flexible measurement techniques that allow you to capture the relevant phenomena and get rapid insights into cabin acoustics.
