Cavity flow phenomena widely exist in all kinds of aerospace vehicles. Research on the complicated physical phenomena in cavities is of great importance to engineering applications. Large eddy simulation method is used to simulate the open cavity noise. We apply high frequency wall vibration at the leading edge of the cavity and investigate its influence on the mode and the noise inside the cavity. The study shows that the peak of the pure tone noise inside the cavity decreases as the frequency of the wall vibration increases. When the vibration frequency at the leading edge reaches 4000 Hz, the peak of the pure tone noise of the main and second mode in the interior of the cavity can be reduced by 15 dB and 17 dB respectively. Therefore, the peak of the pure tone noise inside the cavity can be reduced significantly with the high frequency wall vibration applied at the leading edge of the cavity. This work will pave the way to extend the applications of subsonic open cavities.
