Suppose a sound has to go from point A to B and there is a wall in between:
Is the volume of the sound reaching B louder if the wall is close to A or if the wall is close to B?
The questions come from the fact that in my flat I can hear people shouting in the street, but they cannot hear me shouting. How is that possible? The distance is the same. The only difference is that people in the street is not as close as me to the wall. Does anybody have an explanation?
