Annoying sounds from cars at stop light

Low bass has long wavelengths and can move thru walls or car doors. If an audiophile wants deep bass, a large room is required to let the wave develop and keep in the same room. The interior of a car is tiny and most bass is lost to the outside. You hear the bass louder than the occupants of the car, that is why they turn it up even more..

@oddiofyl (great name, btw) that chart is a great share, thanks! It's interesting reading about the extremely high decibel levels. Crazy stuff!

The bass must sound louder outside the owners car then in it or they would get sick at their stomach. 

I wonder if they put a little dampening behind the drivers if that would help.

viridian you better watch what you say, that is probably my kids you are talking about.............
