There are high chances that if you and your neighbors share a wall or they are downstairs/upstairs from your abode, they can hear the loud noises, the shouting, and maybe even your furniture being moved. If you can hear your neighbors easily from outside, such sounds mentioned above can't be missed from inside.
Can my neighbor hear me through walls?
The sound transfer occurs as a result of airborne noise (voices, music, etc). The airborne sound wave strikes the wall and the pressure variations cause the wall to vibrate. This vibrational energy is transferred through the wall and radiated as airborne sound on the other side.
If noise is seeping into your neighbor's house through paper-thin interior walls, consider putting up a sound barrier like bookshelves. The books and shelves will provide an extra buffer between you and your neighbor, and help absorb any extra noise.
