The aren't. There's an old saying among people who analyze dynamic systems which I learned from a grizzed old pH D back when I was a buck engineer. He said "The universe is well analyzed as if it were composed of interconnected second order differential equations." The point is that writing and solving second order differential equations is relatively easy if you stayed awake during your calculus and physics classes and did your homework, so if you know how to do that, the world is your oyster. We proved it by modeling the front end structure of an automobile, and comparing the movement and velocities produced by our model those measured in a real car crashing into a concrete barrier. The point is that acoustical musical instruments follow the same basic laws of physics. One of the properties of the kind of equations you generally end up writing is that their response always ends up falling off in a 12 dB/octave roll off. Thus, if you look at a recording of any real world musical instrument, its bandwidth always ends up rolling off at some frequency. In the case of cymbals, that frequency is usually on the order of 7-12 KHz, so their bandwidth is always concentrated in the audio range. If you think about it, one ot the things that makes a musical instrument more playable is putting out a fair amount of noise in the audio band whith a reasonable energy input, especially in the bands around 2-4 KHz where the ear is most sensitive. ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=106593 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
