Acoustic absorption products
sound absorbing material
Polyimide-based acoustic absorption materials are lightweight (density of 40-60 Kg/m3), exhibit excellent sound absorption performance (NRC value of 0.80 achievable with a thickness of 25mm), have good thermal insulation properties (thermal conductivity as low as 0.030 at 0 degrees Celsius), boast outstanding fire resistance (compliant with GB 8624 B1 standard, minimal smoke generation), are water-repellent, environmentally friendly (no odor, no formaldehyde release, compliant with EU REACH standards), free from fibers and dust contamination, and easy to install.
Sound-absorbing whiteboard
Integrating sound-absorbing structure with the functionality of a writing whiteboard, it can effectively absorb low-frequency sounds and provide a surface for writing, making it suitable for use in classrooms, training rooms, meeting rooms, and other similar environments.
Improved micro-perforated panel sound absorption module
The improved micro-perforated panel sound absorption module aims to enhance the low-frequency sound absorption performance while keeping the same back cavity depth as the traditional micro-perforated panel structure.
Directional sound amplification products
Outdoor directional speaker arrays for playgrounds
Directional sound amplification products suitable for outdoor playground areas in schools and similar environments aim to concentrate sound energy on the crowd in the playground while significantly reducing noise emissions to unrelated areas. The core technologies include wideband constant beam and wide-beam forming, adaptive beam forming, sidelobe suppression of sound arrays, array unit selection algorithms based on deep learning, and speaker detection technology and systems. These products can achieve uniform coverage in typical playgrounds and offer high speech clarity, minimal ground reflection, and low field boundary sound emissions.
Indoor directional loudspeaker array
Suitable for indoor areas such as inflatable sports venue, large classrooms, auditoriums, etc. It focuses sound in the areas that require reinforcement, ensuring consistent sound imaging and achieving uniform clarity and intelligibility of speech indoors. This helps to avoid excessively high volume in areas that do not require reinforcement and reduce noise interference in nearby areas.
