Hello everyone,

Unfortunately, the planning of the power outlets and LAN cables was not quite optimal. I need a LAN connection in a living room, but it is unfortunately located somewhere else in the room. On the other side of the wall is the children's room, and there is a LAN connection directly there. The walls are drywall, each 1.8 cm thick. I was thinking about making a hole with a hole saw and using a cable guide (see photos) to pull the LAN cable, plugged into the socket in the children's room, through into the adjacent room.
Will I create a problem with sound transmission, so that you can clearly hear in the children's room what is spoken in the next room, because both walls are opened and separated "only" by the cable passage?
Or is this negligible (it should be the same with the power outlets in the two walls)?

Thanks in advance!

By 1.8cm do you mean the respective paneling on both sides? Is there a double socket with two cables or a single socket on the children's room side? -Remove network socket -Drill a small hole through the hollow wall socket to the living room -Install hollow wall socket in the living room -Reroute one or the cable from the children's room to the living room -Install network socket in the living room -Replace network socket in the children's room with a blank cover or close unused port with blank plug

Yes, the issue of sound transmission can thus be exacerbated. However, it depends on the overall situation of the room (windows, doors, etc. - all elements that reduce sound insulation). Specifically, for boxes, you can use decoupled or soundproof boxes, e.g. "the blue ones" from K...., to counteract the problem. For the drywall manufacturers, it can also be found in the datasheet how the installation can be carried out so that no reductions are to be expected.
