For more than 30 years Anotec staff members have been involved in Aircraft Noise Certification, first at an aircraft manufacturer, later as a private company. In this period we have gained extensive experience in all aspects of aircraft noise certification processes. We have leveraged this knowledge to a variety of research projects, where our expertise provided significant added value, and which allowed us to maintain state-of-the-art capabilities. We provide our experience in aircraft noise certification and flight testing to support Policy makers and Regulatory bodies in defining future legislation. Our expertise has also been implemented in our software tools, mostly developed in-house. Thanks to this, we are able to offer a wide range of services to assess and reduce aircraft noise.
