If the door spacing is more than a couple of feet, you can use a spring closer or conventional door latch on one of the doors rather than a pressure latch, as the slight reduction in sealing efficiency will have less of an effect than if the doors were very close.īecause sound travels through solid materials, it's best to use separate door frames rather than one wide one. If you can arrange for a larger gap by building a vestibule‑style airlock, the low frequency isolation will be even better. This doesn't take up any more space than a single door, and a typical wall will leave room for an air gap several inches across. As with walls, the larger the air gap, the better the sound isolation, but where space is limited, it is quite acceptable to use two outward opening doors each side of a single wall. Double-door fitting.Even the best fitting, heavily‑built double door is unlikely to be as effective as a solid wall in keeping sound in or out a double door structure fares better. These work using a tapered plastic wedge screwed to the door frame - as the handle is turned, the door is forced against the seal. Rather than using commercial draught excluders, the most effective way to seal a door is to use a half‑round neoprene gasket fitted to the door frame (including the bottom), in conjunction with a pressure latch. Once the door has been hung, ensure that the seal is airtight all the way round by fitting a proper sealing gasket. Figure 1 shows two approaches to building your own door.

Chipboard is not a structurally strong material so ply is a better choice, but chipboard is viable so long as hardwood inserts are used to take the hinges and the latch mechanism. Door cross-section.Alternatively, you can make your own doors from scratch, using two or more layers of thick ply or chipboard separated by a small gap, which may be filled with Rockwool, fibreglass or softboard to help deaden any vibration of the panels. Two layers of three‑quarter‑inch ply, chipboard or plasterboard fixed to one side of the door will help, but ensure that the frame and hinges will stand the additional weight.įigure 1. The solution is to replace the door with a heavier one or add a heavy layer to the existing door. Even off‑the shelf fire doors are disappointing from the sound isolation point of view unless used in pairs. Internal doors are often very light and offer something like 15dB of sound isolation, which makes them around 30dB worse than a typical wall. Some form of modification is invariably required to bring about a significant increase in sound isolation. And as we know, a vibrating solid object radiates sound.

Using proper seals to eliminate gaps is a help in reducing airborne sound, but is still only a partial solution the mass of doors and windows tends to be much lower than that of the walls, which means that sound generated inside the room will cause them to vibrate. In the case of windows, you can usually spot the leaks by feeling for draughts. Doors can be checked by shining a torch around the edge of the door to see if light leaks through anywhere. They need to be airtight - it only takes a small gap to allow sound to leak through. Doors And Windowsįirstly, check to see how well the doors and windows fit when closed. When all the weak spots have been identified, start by tackling the worst leaks first so that you can get some idea of the degree of improvement as each stage is completed. The weakest points in a typical room are always the doors and windows, so check these first to see which pose the greatest leakage problems. In this case, uprating the existing structure should be adequate. But most private studios don't operate 24 hours a day and tend not to use live drums on a regular basis. Of course, this must be coupled with realistic expectations if you live in a residential area and want to be able to record live music at all hours of the day and night, 'room within a room' construction is pretty essential.

In this case, the only option is to 'uprate' the existing walls, floors, ceilings, doors and windows to achieve an acceptable degree of soundproofing. In the case of the home studio, or even a small commercial studio, a 'room within a room' style of construction is generally out of the question, either on the basis of space or of cost. This month, we examine doors and windows, the most vulnerable areas when it comes to sound leakage.
