Aeroacoustic testing is gaining more and more importance especially in the aerospace and automotive industries. Identifying aerodynamically created sounds and their reduction are the main focus. Beside acoustic optimization, a goal of aeroacoustics is to create a comfortable ambient sound atmosphere in vehicles.
We offer all-round service for investigating and measuring the aeroacoustics of objects in wind tunnels. Many German and international companies of the automotive and aerospace industries rely on our experience in acoustics and aeroacoustics.
Our software solution NoiseImage provides a wide range of advanced analysis functions such as the Clean-SC algorithm. The wind tunnel module allows application-specific settings like applying a shear-layer correction or including the wind speed. Real-time functionality and optimized measurement cycles guarantee quick results in an environment where time is of utmost importance.
On the hardware end, the Microphone Array EVO AC Pro can be optimized for individual wind tunnel applications. Arrays with 120 microphones and more are advisable and our highly-skilled team is able to customize arrays for you regarding object size, desired resolution, price, and many more aspects. Our unique array simulator allows to compare different array geometries (size, number of channels, microphone position) quickly and easily so we can ensure that the final design ideally fits your application and needs.
Additionally, automatic 3D acquisition of the measurement object (e.g. for frequently changing clay objects) can be implemented. This will ensure an even higher mapping accuracy on a true-to-scale 3D model of the object under investigation. This system can be installed directly in the wind tunnel or in a preparation room. A system for auto-fitting of the actual object in the wind tunnel and the 3D model are available as well.
As the entire system is developed in-house, the software and hardware can be tailor-made. The state-of-the-art technology has proved itself in many applications. It is being continuously enhanced and upgraded by our developers in cooperation with international leading aeroacousticians and considering the valuable feedback from our customers.
