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?

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!

"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."

>>>>>>>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.

If this helps, the speed of sound in concrete is about 10 times the speed of sound in air. 
The real answer is both. Sound waves travel through the walls AND make the walls vibrate. 
Yes,  I know it’s a good question. I only ask good questions. How do you get low bass with zero volume? You don’t have to have any experience with headphones to see what I mean.
I get very low bass from my headphones and Walkman CD player. What’s up with that?
