Noise through floors and from upstairs — what can be done
Noise from upstairs comes in two kinds: airborne sound such as voices and TV, and impact sound such as footsteps and dropped objects. Impact noise is best treated at the floor above. From below, an independent sound-insulating ceiling with insulation above it helps — more for airborne sound than for impact.
