Background

Determining the cause of noise production at a building is not easy. This is due to the combination of the size of the building and the often small details in an unknown fluctuating air flow. Existing mathematical models do not yet cover the entire complexity of the flow, which means a limited usability. There are two main reasons:

1. simulation models are a simplification of the complex (partly still unknown) reality, and
2. Computational Fluid Dynamics (CFD) models deal with the large scale of the flow and the small scale of the details that causes whistles.

The use of scale models for measurements is problematic. Details must be scaled in the same proportion as the building and the environment.
