医院学校Aluminum gusset ceilingWhy do you want to choose perforated sound-absorbing aluminum gusset ceiling

医院学校Aluminum gusset ceilingWhy choose perforated sound absorptionAluminum gusset ceiling? Because hospitals and schools belong to densely populated public places, which require a fairly quiet environment; thereforeAluminum gusset ceilingThe sound absorption is very important here.

Aluminum gusset ceilingIt is the use of aluminum gusset plate perforated plate cavity resonance sound absorption structure, according to the sound absorption principle, namelyAluminum gusset ceilingThe cavity resonance sound-absorbing structure formed by setting an air layer behind the perforated sound-absorbing plate is a Helmholtz resonator. The aluminum gusset ceiling is a structure in which a closed cavity is connected to the external space through an opening. When the frequency of the external incident wavef When equal to the natural frequency of the system, the air column in the hole neck vibrates violently due to resonance. In the vibration process, acoustic energy is consumed by overcoming frictional resistance.

医院学校Aluminum gusset ceilingThe reason why the sound-absorbing aluminum gusset plate ceiling can be achieved by perforation:

1）  对于铝合金穿孔吸音板吸声结构，可设该板后空气层划分成许多小空腔，每一个开孔与背后一个小空腔对应。因此，穿孔铝板结构即为许多并联的亥姆霍兹共振

2) The largest sound absorption coefficient is near the resonance frequency. The farther away from the resonance frequency, the smaller the sound absorption coefficient. The experiment also found that the smaller the air movement resistance at the hole neck, the narrower the sound absorption frequency range and the larger the sound absorption coefficient of the resonance frequency.

3) In the high frequency range, the sound absorption coefficient of the structure mainly depends on the size of the perforation rate. The greater the perforation rate, the greater the sound absorption coefficient.

Aluminum gusset ceilingIn addition to being used as a ceiling, the perforated sound-absorbing board can be used as a decorative material for walls, and its noise reduction function can be better played. In addition to the aluminum gusset ceiling of hospital schools, perforated sound-absorbing aluminum gusset ceiling should be selected, industrial plants, various computer rooms, high-end hotels, large shopping malls, exhibition halls, terminal buildings, subway stations, song and dance halls, large opera houses, open indoor buildings It is also very suitable to use perforated sound-absorbing aluminum gusset ceiling as ceiling materials in buildings such as swimming pools.
