Abstract

The invention discloses a sound-absorbing body, comprising a shell (5) and a perforated plate (1) connected with the shell (5), and further comprising a sound-absorbing assembly (2). The sound-absorbing assembly (2) is composed of at least two materials with different acoustic properties and in staggered arrangement. Interfaces (6) of the two different acoustical materials are serrated. The sound-absorbing assembly (2) includes sound-absorbing wedges (3) and sound-absorbing cotton (4). The sound-absorbing cotton (4) is filled between the sound-absorbing wedges (3) and the perforated plate (1).The sound-absorbing assembly (2) may be arranged in multiple layers. The sound absorbing body of the invention has a better sound-absorbing effect.

Description
