We want to present you the results of our work done for the Emigration Museum in Gdynia. We made 23 mobile acoustic screens with dimensions of 190×80 cm, with a very rigid structure. They are made from aluminum, which also allows for easy removal of wheels. These panels have the highest sound absorption class A, in accordance with ISO 11654. They are made entirely from slow-burning materials. Their main task was to reduce the reverberation time in two rooms with a capacity of over 5000m3!
