Metallic Honeycomb Acoustic Liners stand out among numerous materials due to their light weight, high stiffness-to-mass ratio, excellent moisture and fire resistance, and good ductility. Their noise reduction mechanism is primarily based on the unique structure of metallic honeycomb: on one hand, the honeycomb core layer can absorb external vibrations and convert them into deformation energy for gradual release; on the other hand, when sound waves enter the honeycomb structure, they excite vibrations in both the air and the material. Under the effects of friction and viscous resistance, part of the acoustic energy is converted into heat and dissipated, thereby achieving efficient sound attenuation.

Particularly in the aviation field, where aircraft noise reduction standards are stringent and the engine is a primary noise source, the Acoustic Liners within the engine's nacelle are one of the key technologies. Honeycomb structures, owing to their light weight, high strength, high rigidity, and outstanding high-frequency noise reduction performance, can achieve significant weight reduction and noise attenuation within limited space, making them widely used in engine acoustic liners.

Beijing Ander Technologies, leveraging proprietary patents such as its "flexible honeycomb design and manufacturing technology," produces metallic honeycomb acoustic liners that not only feature a high stiffness-to-mass ratio and excellent sound absorption performance but also, through flexible combinations of materials and processes, provides customized, high-performance noise reduction solutions for the aviation and other industrial sectors.
