摘要: The structural influence of the cabin floor on transmission low-frequency propeller noise into aircraft interiors has been examined using a simplified analytical model. response amplitudes and distributions shell displacement internal acoustic pressure are for various frequencies configurations. In general, at lower frequencies, exerts little energy to interior. However, as frequency nears half cylinder ring frequency, can be seen alter significantly response.
