It's an invention that seems as if it would work. I won't put the idea up in here, but I've done a little research and it might just work. I will ask---could a metal box---say 4 or 5 feet long and a couple of feet wide, be constructed with some kind of exposed aperture that when wind blows into/on to/ the aperture---a certain sound would be made? Much like a woodwind instrument when blown into. It would have to be the same sound, fast wind--slow wind.
Sure. All you're doing is providing a column for the air to vibrate in. Think of blowing across the top of a Coke bottle. http://youtu.be/_rhuFGvXARA That "tree" appears to be made from extruded tubes welded and bolted together, but you could roll a sheet of steel, copper, brass, etc. into a tube or form a box and weld, rivet, solder or fold a locking lap seam.
OK. I see. Not exactly the shape i was picturing, but I realize shape doesn't matter. Just that it put out the 'PROPER sound to accomplish what I intend to occur when the sound is made. Now----I suppose the sound made--pitch--loudness --depends on the shape of the aperture. Now we're getting someplace. There is a specific purpose for the particular sound to be made and I suppose that would take some experimentation to obtain. Thanks for responding--------Joel
Think of a pipe organ. Different sizes of the pipe make different notes. Standing Waves and Wind Instruments http://youtu.be/Ne8Jq_UwPSo http://youtu.be/KzvuE7Y48-U
If that was directed at me, I used to build musical instruments.... I just wanted that one in the video to be delivered to my yard.
You can make the tubes square section if you want to. Just remember when you apply the formula, take into account the air temperature. The speed of sound is altered about 1 foot per second per degree F. Faster in warm air, slower in cool. The speed of sound is also faster the more humid the air. I once cut and tuned a 3 1/2 octave set of marimba resonators for an instrument my brother and I played outdoors on the Prado in San Diego's Balboa park. so I estimated 72 degrees F would be a good average for SD as the gigs would be mostly midday November and December, One cool day in the lower sixty's saw a dramatic difference in the tuning, rendering the resonators less than responsive to the drivers, which in this case was a tuned wooden marimba key.
Also interesting. Those round tubes made me re-think the configuration and application of what I want to achieve. Maybe.
