i think it might be because there are fewer sounds to mask the source. normally in the daytime there is a lot of vehicular traffic that can mask many sounds.
another possibility is that once the sun is not heating the air near the surface of the earth comparitively the air higher up is warmer. this has an effect of a temperature gradient where sound propagation originating from near the earth surface is refracted back down to the earth once it reaches the higher warm air. this allows the sound to travel further with less attenuation.

Things are louder at night because the upper atmosphere i.e. stratosphere etc moves closer to the earth and so your sounds waves travel less distance and travel further than they would in the day, plus in the night there is less external noise so again a single noise will seem louder because it stands out. Hope this helps. because the sound absorbing substances like mans,vechilesetc are absent in night.
