To provide evaluation system 2 which can correctly evaluate shock absorption of buffer for human bodies 4.

This evaluation system 2 comprises hammer 6 which gives the buffer for human bodies 4 a shock, and measurement machine 12 which can measure force. The hammer 6 contains bar 20 which can rotate centering on its rear end 40 side, impactor 22, base 26, weight 30, and adjusting member 28 for adjusting natural oscillation. The impactor 22 is located under the bar 20 at the tip 44 of the bar 20. The base 26 is located above the bar 20 at the tip 44 of the bar 20. The weight 30 is located further above this base 26. The adjusting member 28 is located between the base 26 and the weight 30. In this evaluation system 2, natural oscillation of the hammer 6 is desirably within the range of 4 Hz-6 Hz.
