I have just moved into a brand new flat, I realized that the bathroom doors are almost 1 inch above the surface and the way the flat is designed, anybody even uses a tap in the master bedroom bath, a person sitting in the hall can listen to it. Anybody talking in the main hall can be clearly heard in the bathroom. I feel that the sound waves passes through the surface without any obstruction so this could be the reason. If anyone has any solution to this then suggest
