The Structural Structure Of The Aluminum Honeycomb Perforated Acoustic Panel Is A Perforated Panel And A Perforated Back Panel.
Acoustic panels are classified by structure
① Sound-absorbing tip
Sound-absorbing wedge is a special sound-absorbing structure material for strong sound-absorbing field. It is formed and cut by porous (or fibrous) material to make a cone or wedge-shaped sound-absorbing body, which is firm and not deformed. The sound-absorbing wedge is suitable for strong airflow environments. The main object is high-quality anechoic chambers. The absorption of low frequencies is more effective, and it can eliminate standing waves and meet the requirements of eliminating echoes. The low-cut-off frequency sound absorption coefficient is greater than 0.99. Compared with ordinary sound-absorbing wedges, V-shaped and W-shaped sound-absorbing wedges made of polyester have the characteristics of small size and more reasonable price.
② Diffuser
In addition to all the functions of a flat sound-absorbing board, the diffuser sound-absorbing board can also conduct sound waves at different angles through its three-dimensional surface, eliminating the blind area of sound waves during the diffusion process, improving sound quality, balancing sound, thinning accents, and weakening treble , to compensate for the bass.
product structure:
A three-dimensional triangular or cylindrical groove is opened on the front of the MDF, and a structural sound-absorbing material with a circular hole on the back, the surface is painted (color can be selected according to customer requirements), and the fire-proof sound-absorbing cloth is pasted on the back.
Application range:
TV station, cinema, opera house, concert hall, conference center, gymnasium, audio room, home, shopping mall, hotel, karaoke, lounge, restaurant, etc.
③Aluminum honeycomb perforation
The structural structure of the aluminum honeycomb perforated Acoustic panel is a perforated panel and a perforated back panel. The aluminum honeycomb core is directly bonded to an aluminum honeycomb sandwich structure by high-quality adhesives. A layer of sound-absorbing cloth is pasted between the honeycomb core, the panel and the back panel. Because the honeycomb core in the honeycomb aluminum panel is divided into many closed cells, the air flow is blocked, the sound wave is hindered, the sound absorption coefficient is increased (can reach more than 0.9), and the strength of the sheet itself is improved, so that the size of a single sheet can be Make it bigger and further increase the degree of freedom of design. According to the indoor acoustic design, different perforation rates can be designed, and the sound absorption coefficient of the combined structure can be controlled within a certain range, which not only achieves the design effect, but also can reasonably control the cost. By controlling the perforation diameter and hole distance, the perforation rate can be changed according to the customer's requirements. The maximum perforation rate is less than 30%. The hole diameter is generally ∮2.0, ∮2.5, ∮3.0 and other specifications. The perforation requirements for the back panel are the same as those for the front panel. High-quality non-woven and other sound-absorbing materials.
