Turn It Up

If you have two cars parked beside each other, with radios on, both tuned to the same station and each radio with the volume turned up to ‘5,’ (halfway, in other words) is this any louder, in practical terms, than only one car?

The answer to this is so obvious I’m not even going to try to think of what it is.

If you drink two bottles of beer at the same time that are both 5% alcohol by volume will you get any drunker?

Sympathetic vibrations, the same ones that move one tuning fork which was never struck — when placed next to a vibrating fork of the same note (frequency). The effect is more apparent in the bass, since low frequency escapes your automobile much easier than treble.

On a different note, you’ve reminded me of an old idea I had: mobile drive-up theatre. An inverter, digital projector aimed at a white wall, and a small FM stereo transmitter. When I get back home I want to play movies on walls everywhere, pirate style!

Ken, in the trivia on “Brackley Drive-in Radio” that plays before the show starts, there’s mention of a drive-in somewhere in the states that had a personal screen for every car, somehow using mirrors to deliver the picture. I’ll ask Bob Boyle for details.

More importantly, who really only turns their volume as low as ‘5’?
