Aluminum honeycomb perforated sound absorbing ceiling panel

The aluminum honeycomb perforated sound-absorbing ceiling panel features a unique design that combines a perforated aluminum alloy surface panel with a perforated back plate. These components are directly bonded to an aluminum honeycomb core using high-quality adhesives, creating a strong and durable structure. A layer of sound-absorbing fabric is placed between the honeycomb core and both the top and bottom panels, enhancing acoustic performance while maintaining structural integrity.

The honeycomb core consists of numerous closed-cell structures, which effectively restrict air flow and reduce sound wave transmission. This design significantly increases the sound absorption coefficient—often reaching 0.9 or higher—while also improving the mechanical strength of the panel. As a result, larger single panels can be produced, offering greater flexibility in architectural design and installation.

Depending on the acoustic requirements of the space, different perforation rates can be applied to control the overall sound absorption performance within a desired range. This allows for optimal acoustic results while keeping costs manageable. The perforation size and spacing can be adjusted according to customer specifications, with the maximum perforation rate typically limited to less than 30%. Common hole diameters include ∮2.0, ∮2.5, and ∮3.0 mm. Both the front and back panels follow similar perforation standards, and high-quality non-woven fabrics are used as the sound-absorbing material.

This type of ceiling panel is ideal for large public spaces such as subways, theaters, radio and TV studios, textile factories, and other high-standard buildings where effective noise control and aesthetic design are essential. Its combination of durability, efficiency, and versatility makes it a popular choice for modern acoustic solutions.
