Yes... and if that path is by way of the exhaust ducting, it's golden! > That being said, I could design a (relatively) soundproof box > in which to put my computer (or other noisy equipment), but I doubt the > effort required in building the double-studded, triple-insulated > enclosure would really make up for the meager savings in noise. That sounds like overkill. I recall boxes to be used with line and daisy-wheel printers, and they did a remarkable job in reducing the level of noise. (From "very loud" to "a little noisy", mostly. Line printers aren't generally all that quiet.) IIRC, they mostly accomplished this with solid construction (nothing to rattle), baffling (sound-absorbent foam?), and a sort of faceted shape (no or few parallel surfaces), that I assume was to minimize resonance. I'm not an audio geek, however, nor did I ever buy one for my own use (or even consider it).

It might be interesting to build a few different boxes an measure the output. How close can you get to a "soundproof" box on the cheap? -- _ |\_ \| -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
