Annoying sounds from cars at stop light


What causes the stereo in the car next to you at the stop light so loud and annoying with over the top bass and how can the driver stand it?

If it's Friday or Saturday night, follow him, and maybe he will lead you to a tailgate party. One objective of these vehicle setups (my experience comes from my now 23 year old son) is to turn the "whole" vehicle into a speaker system, with the listeners standing together.......outside the vehicle.........  listening and doing .......

"And if it takes 28 feet for the sound to "develop", why can I here that 22Hz note in my 19x15 livingroom so well?" 

Actually I said "fully develop". Very satisfying results can be had with 1/2 or 1/4 wave. For example 12ft. for a 40Hz note will sound fine, I doubt one could really tell the difference, however if one reduces it to a 1/4 wave 7ft., it might not be as authentic sounding. Your 22Hz tone (if authentic), in your room, would be somewhere between 1/4 & 1/2 wave. You would need plenty of power to get 22Hz for full wave.
There is not much musical content below 26Hz unless artificially generated.

So here is a point I would like  to make.

I don't think those low frequency really travel through those walls in your home. 

I would offer this, the waves from the driver hit the wall, they cause the wall to vibrate/resonate and because the wall is much larger then the driver it amplifies the sound. 


The real answer is both. Sound waves travel through the walls AND make the walls vibrate.
