How Does Sound Travel Through Floors

Sound travels through the structure as a vibration. The sound is a wave of energy, and as it hits the structure it is turned into a vibration. That vibration makes its way through all of the hard surfaces that come in contact with each other and come out the other side as an airborne sound.

Does sound travel up or down in a flat?

Sound doesn’t travel upward or downward in an apartment. Sound travels in all directions equally unless you make some modifications or you seek to guide the sound in a particular direction.

Is noise louder at higher floor?

Higher is noisier – noise travels upwards and that is why higher floors tend to be noisier (it usually starts to reduce from around the 15th floor). Banging from construction work nearby can be heard acutely on higher floors even through the source of the noise can seem very far away.
