Zusammenfassung:	The invention relates to a micro-hole sound-absorbing structure in the field of environment noise control technology. It comprises one or a plurality of sound-absorbing structure units, a supporter and a back board. The sound-absorbing structure unit comprises two layers of net and an interlayer particle; the particle size is bigger than the size of the net-hole; the particle is partly embedded in the net hole. One or a plurality of sound-absorbing structure units is fixed on the back board to form the micro-hole sound-absorbing structure. There is the air gap between the sound-absorbing structure unit and the back board.
