Adjacent offices that share a common wall will also share the bleed of noise from room to room. Part of this is inevitable, but much of it is controllable if the right treatments are applied. Start with the wall and understand that a common metal frame supporting drywall on both sides will serve the equal to a string pulled tight between two coffee cans. It is the “vibration” that will carry sound waves from room to room and impact confidentiality. The key to your treatment is to add “density” to the wall and then “disconnect” the assembly to force the collapse of the transmitting sound wave. Density comes in the form of dB-Bloc, a thin weighted sound barrier material that can applied direct to your finished wall. Disconnection comes from a channel system over the top of the dB-Bloc, and a new layer of drywall then attached ot the channels. This combination forces the break in transmitting vibrations and will protect one rooms noise from the next.
But you’re not done. Offices with ceiling tile systems will also share plenum space. Ceiling tiles do not in and of themselves block noise from bleeding into our out of a room. They need help, so be sure to layer the right material above the ceiling tiles and no, this isn’t just batting insulation. That material again carries no density, it can’t hold the noise. But what can is a product called a Ceiling Cap. These are plates that rest atop ceiling tiles to combat sound bleed.
Put these treatments into play and trigger up to a 90% collapse in sound bleed from office to office. For help with your treatment, call NetWell Noise Control at 1-800-638-9355.
