An acoustic door should be selected around the room's noise-control requirements, not just its appearance or thickness. For recording studios, livestream rooms, TV facilities and meeting rooms, the door leaf, frame, perimeter seals and bottom seal work together to reduce sound passing through the doorway.
Shenghao Doors offers configurable soundproof door designs with plain-colour, wood-grain, upholstered and mixed finishes. Start by confirming your intended use and acoustic target, then match the opening layout and hardware to everyday operation.

Our product range includes 30, 35, 40, 45 and 52 dB options for assessment against a project's requirements. These are different configuration choices; one door does not provide every rating. Confirm the relevant report, measurement method, sample size and complete tested construction before specifying a value.
| Application | What to discuss before ordering |
|---|---|
| Recording and voiceover room | Noise from adjacent rooms, background sound and sealing continuity |
| Livestream or podcast room | Equipment noise, access frequency and any vision panel |
| Meeting room | Speech privacy, closing operation and door access |
| KTV or home cinema | Music transmission, wall construction and adjacent spaces |
A laboratory door rating and the noise difference measured in your room are not interchangeable. Sound can also travel through walls, ceilings, ducts and construction gaps.
Even a substantial door leaf can be undermined by gaps around the frame or at the floor. Confirm the perimeter gasket, frame-to-wall joint and door-bottom arrangement. The chosen threshold or drop seal should suit the finished floor and remain in contact when the door is closed.
Ask how the lock or latch holds the leaf against its seals. A door that looks closed but does not compress its gaskets consistently may leave an avoidable sound path.
A single leaf simplifies daily access where the passage width is sufficient. Double leaves provide a wider passage but need suitable sealing at the meeting stile. A two-door arrangement can be discussed for particular room layouts, but its performance must be assessed as a complete arrangement rather than by adding two individual ratings together.
A circular or rectangular observation window can help staff see whether a room is occupied. It should be selected as part of the acoustic construction, with suitable glazing and edge sealing. Adding a window to a tested opaque door does not automatically preserve the original rating.
Specify hinges, lock, closer and access-control hardware alongside the required opening direction. Heavy doors need hardware appropriate to the leaf weight. Upholstered and wood-grain finishes can suit creative spaces, while plain finishes can coordinate with offices and equipment rooms.
Measure the opening width and height at three positions and record the finished wall thickness. Provide the finished floor level, opening direction, hinge side and lock side on a drawing. Share photographs where walls are uneven or the doorway includes a return wall.
Confirm whether the quotation covers the leaf, frame, seals, hardware, vision panel, packing and installation. These details make comparisons between acoustic door suppliers more useful than comparing one price per door.
Thickness is only one factor. Compare the complete structure, seals, glazing and applicable acoustic evidence.
Yes, finish options are available for discussion. Confirm the finish against the selected acoustic construction and approved sample.
Room performance depends on the complete enclosure and installation. Establish a realistic target for the actual noise sources.
