Quiet Spaces Need Proper Sound Protection
The product from Jingsheng Home Furnishings Co., Ltd. create peaceful environments for rest and work. Bedrooms need quiet for good sleep. Studies need quiet for focus. Meeting rooms need quiet for private conversations. Hotel rooms need quiet for guest satisfaction. Our Interior Sound Proof Doors reduce noise at every point. The door leaf is 45mm thick. The internal core uses bridge-hole board or aluminum honeycomb sound-absorbing material. Both materials have many tiny holes. Sound waves bounce around inside these holes. They lose energy and cannot pass through. The airborne sound insulation reaches 35dB or more. This meets GB/T 19889.3 and ISO 140-3 acoustic test standards. What does 35dB mean in real life? Normal conversation is about 60dB. After passing through this door, only about 25dB reaches the other side. You can barely make out what people are saying. The Interior Sound Proof Doors give you real acoustic privacy.
Full Perimeter Sealing Eliminates Sound Leaks
The gap between door and frame is the main path for sound leakage. Many doors have good sound insulation in the leaf itself. But gaps around the edges ruin the effect. We install EPDM magnetic sealing strips around the full door perimeter. When the door closes, magnetic force pulls the seal firmly against the frame. This creates a complete ring of sealing. We add an automatic drop-down seal at the bottom. When the door closes, the seal drops down to block the gap under the door. When the door opens, the seal lifts up. It does not affect normal operation. This gives you full perimeter sealing with no gaps. Sound has no path to escape. Standard hardware includes a silent magnetic lock. Traditional locks make a clicking sound when the latch hits the strike plate. This noise is especially noticeable at night. Our magnetic lock makes almost no sound. Opening and closing noise stays below 30dB. That is quieter than a whisper. The hinges come with damping buffers. Doors open and close smoothly without sudden impact. Cycle life exceeds 80,000 tests. The sealing system also provides dustproof, insect-proof, and thermal insulation benefits. In air-conditioned or heated spaces, good seals reduce energy loss.
Applications for Noise-Sensitive Environments
These product work in many settings. Home bedrooms, studies, and home theaters are classic applications. High-end hotel rooms demand good sound insulation. Office meeting rooms, manager offices, and live streaming rooms need conversation privacy. Hospital wards require quiet healing environments. Long-term rental apartments benefit from sound control between units. Recording studios and practice rooms also use these doors as auxiliary sound barriers. Our factory holds ISO 9001 certification. Production, quality control, and shipping follow standardized processes. Pre-sales staff discuss your needs and recommend the right soundproofing solution. During production, we share progress updates. After-sales staff handle follow-ups and repairs. Warranty is 1 to 2 years. We support OEM and ODM customization. Sample production takes 10 to 15 days. The Interior Sound Proof Doors help you create quieter, more comfortable spaces.
