Why, when I hear lighting from 8 miles away, does the thunder sound longer?

The sound from the thunder takes many different paths to you. When it's close, the path differences are so small that you receive the sounds close together. When it's far, the distance difference between the different paths become much greater and you receive the sounds over a longer period of time.
