I have read that it is better to run your electrical wiring on the surface through wiremold and boxes than to mount it flush in the walls, because it will create less sound leakage. True or false?

OB -
It's true, the more holes you cut into the drywall (ie: for wall boxes, recessed lights, etc.) the more sound escapes from the room.
Personally, I put all the electrical / audio boxes in the wall... making sure the boxes were not lined up. For instance, I have two boxes separated by two 2x6s and lots of cellulose insulation.
Hope this helps.

No, it won't leak sound but if you run power lines parallel with signal lines, it can induce 60 or 120 cycle hum on your audio. Just keep your signal carrying lines at least 18" away from power cables if they run parallel and if they have to cross each other at some point, do so at 90 degree angles.

I want my studio to be solid acoustically but a nice appearance is desireable too. I just can't stand the thought of wiremold and outlet boxes sticking out instead of flush in my brand new walls. Not to mention they'll get hit moving stuff around. Nahh, I'll come up with something.

DD, you WILL lose a little soundproofing that way, but you can minimise the loss by offsetting boxes (none back-to-back, or even in the same 2' wide stud cavity) and SEALING EVERYTHING! Butyl caulk is not just your friend, it's your god... even a 1/64" gap can negate half your efforts at building a sound proof wall.
That is why even NECESSARY openings need to be multi-baffled. That's why HVAC costs so much more for a studio. You have to run separate, large cross-section, convoluted ducts SEPARATELY from the (shock-mounted) source to EACH room or else don't waste the effort building special walls. Wiring needs to enter thru baffled conduits or special caulkable condolets to avoid leakage. Don't run any plumbing thru sound walls unless you like the water noise in your recordings.
Some people run wiremold at heights that will allow wall treatments to "sit on it" and look less conspicuous. remember, everything that goes in the wall in place of insulation/sound deadening lessens the effectiveness of the wall.

Click on STC charts, scroll down near the bottom... with this good a wall, you could afford a little loss. Just remember that caulking gun... Steve

While we're on the subject, do you know of a website, literature, or anything else I can read up on to better understand the special HVAC requirements of a studio? I'm 100% sure that none of the HVAC companies around here have ever done this kind of install. At least I'll only have 3 rooms. Control room, live room and vocal booth. Oh, I'll have a bathroom too but they should be outa there but they start sweating anyhow

These guys are at least in the same state, and claim to have done at least one major studio -

Everest mentions that noise is about the 5th power of velocity, so a slow squirrelcage large blower would seem like a good thing - no direct contact with the building of course; I'm still looking for a good source - maybe major manuf's sites would have studio areas...
If you haven't already been there, just found this - looks like about a week's worth of broadband cruising at first glance -

Gotta go check em out, if I see anything useful I'll bookmark it and get back to you... Steve
