YT2095 Posted August 17, 2003 Share Posted August 17, 2003 answering a question in the "pre-echo" thread, I came upon an interesting idea/invention, allow me to try it out on ya`ll have you ever been driving down a Motorway/highway/Autoban an encountered those rumble strips, like mini speed bumps that vibrate the hell out of your car? well applying the same principal as used in the grooves of a record, these strips could be lain in such a way so as to not only just vibrate, but give an audible/vocal message as well! the closer the strips the higher the pitch and furter appart the lower the pitch and so on. a "STAY AWAKE" or "Sharp bend approaching" etc.. message could be embeded into these bumps, a bit like a bar code. now It wouldn`t suit ALL circumstances sure, wet weather, radio on etc... but if it elliminated say 20% of accidents in a trouble spot, it would be worth it, and wouldn`t cost that much to do with a computer and a strip laying machine Subliminal effects could be used ti mimik brain patterns to stimulate alertness if you didn`t want to go the audio/vocal path.

Kedas Posted August 17, 2003 Share Posted August 17, 2003 I think you would have to drive very fast to understand what he/she is saying. and the words would be 'drive slower' About 150Hz is probably the best you can get. Link to comment Share on other sites More sharing options...
YT2095 Posted August 17, 2003 Author Share Posted August 17, 2003 good point actualy with regards to the vocal bit. I calculate at 50kph and 100 strips per meter 231.48 Hz would be the best you`de get but the brain wave patern to stimulate alertness might work?

Kedas Posted August 17, 2003 Share Posted August 17, 2003 The dampers of the car are your sound filter. This will probably determine the max frequency. 'brain wave' pattern stimulation maybe but it's a dangerous thing to force that to someone certainly because you do not control the 'right' frequency. some have bad influance.

YT2095 Posted August 17, 2003 Author Share Posted August 17, 2003 yeah, I hear that 7Hz can be quite nasty if not fatal at sufficient power oh well, back to the drawing board ) Link to comment Share on other sites More sharing options...
blike Posted August 17, 2003 Share Posted August 17, 2003 Couldn't you just move the strips closer together? Link to comment Share on other sites More sharing options...
