This device is used to characterise the impedance and transmission loss properties of materials, in the frequency range of 50Hz-6.4kHz. Material samples with a diameter of 29mm and 100mm can be evaluated in the frequenc…
View recordThe experimental test is conducted in the wind tunnel in combination with the test rig. The wind tunnel is exclusively designed for speed racing purpose with low turbulence intensity and steady dynamic pressure. The tes…
View recordIn aeroacoustics, the far-field directivity is often computed using the integral solution of the acoustic analogy equations. The sound prediction prediction can be rendered when the turbulent eddies move across the inte…
View recordThis facility was designed and fabricated at HKUST, and it is used to evaluate prototype acoustic materials. Test samples are sandwiched tightly between two paralleled Plexi glass plates (2.4 m x 1.2 m x 0.02 m), which …
