Hello Terry and welcome to the Cow Audio Forum.
Peter, Eric and Bill have all made good cases and they don’t necessarily agree. That’s not that unusual.
I have had success with a boomed hypercardioid Schoeps cmc641 more frequently than with a lav. My situations are apparently different than Bill’s. My corporate clients don’t want to see lavs.
Our air conditioning varies, certainly, but in commercial and industrial spaces, I have been able to find places that are acceptably quiet for interviews. Maybe our building codes are different back east. Maybe we spec larger duct work that lowers HVAC noise. Maybe BIll needs to dig his heels in more when locations are chosen. When those places are chosen, I’m usually there to say, “nope, but try over here.” I have stopped being amazed that some shooters completely ignore the acoustics and ambient noise levels. The fight has gotten easier over the years. I’m not sure why. I tell producers if and when I hear problems. I hand the headphones to them and ask them to verbally sign off of the sound level so he can’t come back on me and say it was my fault.
I have very poor luck burying a lav under a suit jacket and making it usable. As a result, for efficacy, and because my clients don’t want to see lavs, the boom with a cmc641 works on interiors more often than not. Professional talent are more accommodating when I want to use a Rycote stickie to place a lav on the sternum, between the breasts of male or female talent. The “regular guy or gal” may be a bit freaked by that, maybe not. The CEO is much less likely to say, “OK, sure, shave a 2″ square on my chest to plant your mic.”
I frequently use my locked down boom rig and hang the boom from the top just out of frame. The locked down boom totally eliminates disagreements between the shooter and boomer when the boom ends up in the shot. At least half of the time, this happens because the shooter zoomed out to far or angled up a bit and caught the boom. If the boom doesn’t move, it’s not the boomer’s fault. End of discussion. 🙂
Camera height has everything to do with where the boom ends up and how close you can set it. The further below the eyeline the camera sits, the higher the boom has to be placed. Setting the lens at eye level is a good place to start.
The Schoeps has some extraordinary capabilities. I have angled it straight down when there is noise coming in from front and back. I have angled it toward the face with the boom slightly in front of the head to reduce ambient noise from a loud camera or other noise on the camera side. Even with the talent somewhat off-axis, the Schoeps sounds great.
Boomed with a cmc641, not laved, even with the baseball hats:

Get some sound blankets to lay down as many places as you can to knock the bounce down.
You simply need to take the time to listen to figure all of this out. It doesn’t take much time, and you can really improve what you get. Good headphones are a must. I strongly suggest Sony MDR7506. $99 most places.
