Professional-grade soundproof door

The Professional-grade Soundproof Door is a high-performance standardized Sound Insulation Door developed based on the national building standard design atlas 04J610-1. Optimized through professional experimental communication and technical verification with Tsinghua University, this acoustic door adopts scientific structural design and acoustic configuration to deliver reliable and stable noise isolation performance. It achieves a professional sound insulation index ranging from RW 30dB to 45dB, effectively blocking medium and low-frequency ambient noise as well as daily environmental noise, fully meeting the acoustic requirements of commercial, industrial and architectural decoration projects. The door’s internal structure is densely filled with high-quality Sound Absorbing Cotton, which fully absorbs and dissipates penetrating sound waves to eliminate residual noise. Built-in Shock Absorbing Board effectively suppresses structural vibration and acoustic resonance caused by sound p…
