Why do passing cars sound louder from a height?


I live in a second-floor apartment which overlooks parkland that’s bordered by a busy road [(https://i.postimg.cc/wTm2PsgL/Overhead-apartment.jpg)]. Why do the passing cars sound much louder from my apartment balcony than if I stand the same distance (40m) from the road at ground level?

In: Physics

The terrain, the shape of buildings, and the materials used in those buildings are creating a situation where more of the sound reaches your balcony than it does from another. There are too many variables to be able to figure out your specific situation.
