Only those irregularities that allow the sound to be reflected back to the micorphone will do so, and that would require a reflecting surface perpendicular (or close to it) to the angle at which the sound wave hits the ground. Soundwaves hitting flat ground will reflect away, not back.ecktronic said:I dont beleive that would be true in the desert. There would be echos and reverberations from the ground.
Plus, unless those irregularities were the size of a large boulder or wall or somthing, only the highest frequencies would be reflected because the wavelengths of the lower sounds would just swamp the obsticles.
And finally, much depends upon the texture of the ground. The harder the ground the more it will reflect; the looser, more it will absorb. Hard drypack dirt will reflect far better than sandy loam or desert wildflowers, etc. But then again, hard drypack dirt will reflect the sound away, not back towards the mic. The majority of reflection will be coming from first reflections betweeen the source and the mic, beyond that, in an open field they'll approach zero.
You're right, it's not a pefect anechoic environment, but if you're talking relatively flat surrounding terrain with open horizons, it's about as close as you can get without tiling a 10 ft circle of the ground around the mic in foam pyramids
.
No, of course not. I was talking acoustics. Hell, you'll also have sounds of wildlife, overhead aircraft, and stuff like that too.Plus the wind would definetly not make a desert recording sound like an anechoic chamber recording.
