AI Technical Summary
Existing sound-absorbing panels have simple structures and poor sound absorption effects, which cannot meet the increasingly stringent noise reduction requirements.
It adopts a multi-layer structure design, combining an outer wood panel, a middle sound-absorbing panel, and an inner sound-absorbing panel. It utilizes fiberglass cloth and sound-absorbing holes to form an integrated sound-absorbing hole, combined with rock wool and ceramic sand to improve sound absorption performance, and is fixed and connected with glue.
It significantly increases the number of sound wave reflections and absorption rate, improving the overall noise reduction performance of the sound-absorbing panel, and features environmental protection, fire resistance, water resistance, and stain resistance.

Abstract
Claims
1. A sound-absorbing panel for building decoration with good noise reduction performance, characterized in that: The sound-absorbing panel consists of an outer wood panel (1), a fiberglass cloth (2), a middle sound-absorbing panel (3), and an inner sound-absorbing panel (4) from the outside to the inside. The outer wood panel (1) is densely covered with cylindrical through holes (5), the fiberglass cloth (2) has a porous mesh structure, and the middle sound-absorbing board (3) is provided with pores (6) that communicate with the through holes. The smaller end of the pore (6) faces the fiberglass cloth (2), and the larger end of the pore (6) faces the inner sound-absorbing board (4). The inner sound-absorbing plate (4) is densely covered with grooves (7) corresponding to the middle sound-absorbing plate (3). The through holes (5) are connected with the fiberglass cloth (2), the pores (6) on the middle sound-absorbing plate (3) and the grooves (7) on the inner sound-absorbing plate (4) to form an integrated sound-absorbing hole.
2. The building decoration sound-absorbing board with good noise reduction performance according to claim 1, characterized in that: The adjacent components of the outer wood panel (1), fiberglass cloth (2), middle sound-absorbing panel (3) and inner sound-absorbing panel (4) are fixedly connected by glue.
3. The building decoration sound-absorbing board with good noise reduction performance according to claim 1, characterized in that: The through hole (5) is completely connected to the pores (6) on the fiberglass cloth (2), the middle sound-absorbing plate (3), and the groove (7) on the inner sound-absorbing plate (4).
4. The building decoration sound-absorbing board with good noise reduction performance according to claim 1, characterized in that: The width of the smaller end of the opening of the pore (6) is equal to the diameter of the through hole (5), and the width of the larger end of the opening of the pore (6) is equal to the width of the groove (7). The lengths of the pore (6) and the groove (7) are equal, and the total area of the smaller end of the pore (6) is just enough to completely cover the area of all the through holes (5).
5. The building decoration sound-absorbing board with good noise reduction performance according to claim 1, characterized in that: The intermediate sound-absorbing plate (3) is made of rock wool, and the inner sound-absorbing plate (4) is made of ceramic sand.
