I was just skateboarding at lunch... we've been bombing hills out in the Santa Cruz mountains. Anyway, we dropped down this fast pitch of a divided, 2 level street, where one direction is about 10 feet higher than the opposite direction. The lower path wall being reinforced with the corrugated siding, separated by something like 6" x 6" wood posts. The first time we passed it my partner said he thought he had a wheel coming loose or something. The next time around, I listened for it, and it was the sound of my wheels on the asphalt reflected back, doppler effect and all. We probably go past that wall at about 25 mph, maybe 3-5 feet away from it. -Miko >>> "Michael LaMeyer" <m.lameyer@verizon.net> 08/22/01 10:03AM >>> If you play something really loud (further back is better) at the broad side of a building covered with vertical corrugated siding, and then dance wildly back and forth between the building and the sound source, you get the equivalent of a physical comb filter/phaser. If you can find two buildings like this parallel to each other, it hurts.
