Noise Reduction Technologies with Meta-materials

10 - 14 February 2020

Venue: Lorentz Center@Snellius

If you are registered for this workshop, you have received login details by email.

The workshop theme focuses on a series of technological advances and scientific studies, which, in the last decade, have been carried out with the aim of reducing the acoustic noise of aircraft, wind‑turbine blades and many other mechanical systems.
