Comments on Inferno Sonic Barrier Is A Sonabarrier
The Inferno device is intended to create a barrier impassable by human beings. (Read
the complete story)
| "Great. Use it to keep birds away from wind turbines." (Andy 4/3/2008 9:17:50 AM) |
| ""...define an area in which human beings could not enter."
As long as they don't have a 59 cent pair of earplugs. Or does this freq. somehow penetrate the skull?" (duG 4/3/2008 1:39:16 PM) |
| "Andy - interesting idea. It turns out that particular wind turbine designs have five times the mortality rate than others; the average is about 2 birds per turbine per year overall. However, it's also true that birds are killed at a high rate by vehicles, and even just running into windows in houses and buildings. Still a good idea, though." (Bill Christensen 4/3/2008 2:02:28 PM) |
| "duG - The entire body is sensitive to vibration, particularly in this range. I used to work for the auto companies, and was able to take course in vehicle dynamics taught by engineers with lots of experience. There is a lot of testing done relating to vibration in the passenger compartment; even at relatively low noise levels, poorly handled vibration can have drastic effects on passenger experience. You'll feel it right in your gut and chest." (Bill Christensen 4/3/2008 2:06:43 PM) |
| "That particular frequency range is vital to human hearing. If you can't hear it, other people's voices are muffled and hard to understand. Sounds loud enough to drive people from a room are loud enough to do damage. This sounds like a very dangerous device." (that ringing in your ear is not necessarily going 4/6/2008 10:37:41 PM) |
