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?

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."

>>>>>>>Uh, that's how sound waves propagate through ANY medium, air, water or walls, or whatever. The acoustic waves excite the molecules of the medium. Also, if the walls amplified the sound, the voices you hear from the next room, on the other side of the wall, would be louder, not softer.

I would agree Elizabeth. Pretty accurate read on the issue. Sound waves are altered, Some frequencies don't fare well in sheet rock and lose amplitude. Others, like the dreaded 80Hz bass notes, ( those lease busters ) get amplified.

Alternative explanation: the poor guy upstairs or in the next apartment only hears the bass frequencies but not the rest of the frequencies. That’s why the sound is irritating, it’s just the thump, thump of the bass, not because the bass is amplified. The wall absorbs higher frequencies better than low frequencies.  If it was true walls amplified bass frequencies you could get better bass by constructing a wall in front of your speakers. Hel- loo!

My sound system makes a glorious sound at lights. It's called a Hemi.
