Use and characterisation of new acoustic treatments and tools
Budapest (Hungary), 16-18 December 2019
DENORMS Action’s 5th Training School “Use and characterisation of new acoustic treatments and tools” was held from 16th to 18th December 2019 in Budapest (Hungary), organised by Óbuda University.
This Training school was aimed at the industrial partners and Early Career Investigators. The training was offered in both theoretical and experimental aspects of developing new sound absorbing and sound controlling structures.
During the first day, the refresher training courses were organised covering the basic theory of sound interaction with porous materials and metamaterials. During the following two days lectures and practical sessions familiarised the audience with the new methods used in design of conventional and metamaterial based noise reducing treatments.
