description: This deposit is the programme of the 23<sup>rd</sup> CEAS-ASC Workshop occurred at the Roma Tre University. In 2019, this event was the yearly-based scientific workshop of the ANIMA project. The topic of this workshop help on the 26-27 September 2019 was about <strong>New Materials for Applications in Aeroacoustics</strong>.
