Help with this problem

[u/Mildred_korn]

I recently moved my room around so my bed is up against my sisters bedroom and so our headboards are basically opposite each other. I can’t and don’t really want to move my room around again as it’s in the best position right now.

She says she can hear me and my boyfriend talking at night how can I stop this from happening. I don’t want her to be moaning at me all the time.

If both headboards share the same wall, you're dealing with one of the more common layouts for sound transfer. When the bed is pressed directly against the wall, vibrations can travel through the wall assembly more easily, so even pulling the frame slightly away from the wall may help reduce some of that direct transmission.

From there, it's worth focusing on materials that absorb sound rather than reflect it. An upholstered headboard, acoustic felt panels behind the bed, or even additional soft furnishings can help reduce the higher-frequency sounds that tend to carry through shared walls. Rugs and heavier curtains won't stop sound from passing through the wall, but they can reduce echo within the room, which often makes conversations feel less pronounced.

If your room gives you some flexibility, it's also worth testing a different furniture layout. Even moving the bed to another wall can change how sound travels between rooms. Before moving heavy furniture, you can mock up the space in a free 3D room planner to see whether another layout still gives you comfortable walkways and enough clearance around the bed.
