Sound insulation system of fossil fragments and applied fossil fragments

The utility model discloses a fossil fragments have two terminal surfaces on the body, form at least one recess and/or arch between two terminal surfaces. Furthermore, the utility model also discloses a sound insulation system of using above -mentioned fossil fragments. The utility model discloses in, two terminal surfaces respectively with two sound insulation system's of outside wall contact, simultaneously, owing to formed at least one recess and/or arch between two terminal surfaces, so for traditional Z shape fossil fragments or I -shaped fossil fragments, under two the same condition of terminal surfaces distance, sound is propagated to another terminal surface on from a terminal surface, the propagation distance that has recess and/or bellied fossil fragments sound is obviously longer than Z shape fossil fragments or I -shaped fossil fragments. Consequently, have the recess and/or bellied fossil fragments can play bigger decay to sound. Thereby will the utility model discloses a when fossil fragments are applied to sound insulation system or are given sound insulation in the wall, play better syllable -dividing effect.
