Natural Science Forum / Physics / Acoustics / November 2007

In all these, acoustics has disappeared.

Utility wants to add a second 10MVA transformer close to an existing

on average, but with nearly pure tones at 120 Hz, in phase, won't we
get interference patterns with 6 dB peaks compared to a single unit.

    FYI, the Megaconference (www.megaconference.org) is now in progress
LIVE and will be for a total of 24 hours, about 9am now through 9am
tomorrow. Though replays will be available ad nauseam.
