The thing that makes me laugh about these 'boomboxes' is how proud the owners seem to be about the sound they are making.

It usually has a very high level of distortion, very little true bass - it's just very loud - and the car it's in usually rattles like anything.

I once read something about an experiment they did in Paris a long time ago. They built a special horn to generate sound at AIR 8 or 10 Hz, switched it on and caused a total panic - the building had to be evacuated. It turns out that true subsonic frequencies at any real volume cause uncontrollable panic and nausea.

Pity there isn't any real low frequency sound in what those 'boomboxes' are shovelling out...
