...after looking around, I'm having a (single phase) Oneida 1.5 hp. system shipped to me this week - will post after I've had it hooked up - they claim 75-80 db (Leeson 3450 rpm motor) and also offer a silencer to further reduce noise.? I've also built a simple relay system that allows control of my dust collector from any machine location - control wires @ 24 volt, so any small 2-wire jacketed wire works great (phone wire, thermostat cable, etc.) simple off-the-shelf Grainger parts, about $35 in parts.? Email me off list if you want specifics.

It's been my experience that noise in fan systems is almost always a fan balance problem - cheap collectors are notorious for out-of-balance fans - Oneida offers a balanced refit for the 2hp Taiwanese fans that's supposed to cut noise and vibration tremendously.? I'm surprised that fan noise would be much affected by the speed difference between a 50hz and 60hz motor - suspect that Felder's fan source has some QC issues...

Hearing protection is critical!!!? Those who know about these things claim that 5 minutes exposure to levels exceeded in woodworking can cause permanent and irreparable damage - I've got 30 years in the trades, and, like a fool, worked without hearing protection during the first part (as we were all too macho to wear headphones), causing significant hearing loss.? My solution, after trying every headphone available, is to go with the cheapie foam plugs (connected with an orange plastic cord - Grainger again...) AT ALL TIMES!? They're comfortable enough to wear all day, and you can converse while wearing them when the machinery is off.? I've got a set of Peltor phones for short -term realy noisy stuff like planing - they'll knock off a couple more db than the plugs.? Like everything else, hearing protection becomes a habit -
