The invention provides a sound insulation pad data determination method and device and electronic equipment. The method comprises the steps of determining the noise reduction amount of a path from each point source to the ear position of a driver according to the sound field data of the point sources in different sub-regions when the surface density of a heavy layer is designed, wherein the path noise reduction amount comprises path attenuation amount, namely, the path noise reduction amount from different point sources to the human ear position of the driver needs to be determined independently, so that the designed heavy layer is more accurate. 本发明提供了一种隔音垫数据的确定方法、装置及电子设备，在设计重层的面密度时，需要根据位于不同子区域的点源的声场数据，确定每一所述点源到驾驶员人耳位置的路径降噪量；所述路径降噪量包括路径衰减量，即不同点源到驾驶员人耳位置的路径降噪量需要单独确定，进而设计的重层更加准确。
