The "Acoustics Laboratory – Acoustic Measurements" is a space dedicated to the experimental characterization of the acoustic properties of porous sound-absorbing materials. The primary activity consists of measuring sound absorption and other relevant physical parameters using standardized techniques. The laboratory is equipped with three impedance tubes: two employ the standing wave ratio (SWR) method, suitable for medium-high frequencies, while the third uses the transfer matrix method with three microphones, which allows for a more detailed and precise analysis of the acoustic properties of materials across a wide frequency range. To support experimental and prototyping activities, the laboratory also has an Elegoo Saturn 2 3D printer for producing customized samples and supports. Furthermore, there is equipment dedicated to measuring flow resistance, a key parameter in the acoustic modeling of porous sound-absorbing materials.
