Sound Insulation Study on Mg Sheet and Mg Honeycomb Panels

Abstract:

Article Preview

The sound insulation experiments were conducted to magnesium alloy sheet and magnesium honeycomb panels. It is found that the sound insulation coefficient (transmission loss, TL) of honeycomb panel is higher than that of the sheet in full sound frequency spectra, and TL spectra of both single sheet and honeycomb panel is similar with the sound frequency, thus the TL is increased obviously with the frequency. Comparably, TL of honeycomb panels is always higher than that of the sheets, especially at middle range of frequencies 6 kHz~10 kHz, the sheet has a TL of 27 to 31dB, and the honeycomb panel has 34-39 dB. The parameters of honeycomb cores is discussed briefly.
