Sound isolation for wood stove stovepipe / chimney?

I'm installing a wood stove in a recording room and I'm concerned about sound coming in from the chimney.  Any suggestions for dealing with this?

There is a consistent noise source nearby which, so far, I have dealt with relatively successfully with window/door plugs.  The stove would open a 6" channel from the room, through the ceiling/attic, and through the roof.

The stove itself might have enough mass to stop the sound (?) but the stovepipe is made of thin metal.

Sound isolation - dealing with HVAC ducts

OK, so I'm planning a room. It's a 15x30 basement room. Along the 30 foot length, there are is one HVAC duct on each side running along the ceiling with vents into the living room above. I have the ceiling pretty much figured out except how to deal with these ducts. I have other ventilation plans so I won't be using them. I just can't figure out for the life of me how to insulate them for sound isolation. I can't move or modify them.

Thanks in advance for any suggestions.

Help isolating recorded noises and whispers when asleep

Long story short, I keep hearing sh*t in my house, it sounds like people talking and I hear running around etc. We have cameras in our house, but they keep magically looking very grainy, I used voice amplifier but magically again...when I suspect anything..it sounds like my ear is blown off when listening...so I recorded our cameras from my phone on certain nights. and when I try to playback the audio I hear the whispers.

Which gear needs to be plugged into isolation transformer?

Hey ive been thinking about deliver clean power to my rig as it approaches completion. The use of isolation transformers seems to make sense since the rig will be in a regular house, without any modifications to the existing electric service. My questions are:

1. What pieces of gear need to be plugged into an isolation transformer?

Walls: Sound Isolation in Room with Foam Concrete Slab Insulation

I'm planning to sound-isolate an already-converted garage built on concrete slab. I want to modify the walls to have mass-air-mass with two layers of drywall inside and out.

The room has rigid foam insulation around the slab that protrudes into the room. The insulation, framing, and the drywall installed over it take up an additional 6"+ around the room perimeter. It seems the only way not to disturb the insulation is to add parallel framing on the inside, which I'd really like to avoid.

Builder recommendations in Eastern US-CT: vocal isolation booth, ~7'x12'

Forums

I have an 8'x12' corner available within a larger room (with 8' ceiling) for a vocal isolation booth.

Any builder recommendations in the Eastern Connecticut area who can get it quiet in there? I'm on the fence about doing it myself - if I can avoid construction I'd like to.

Thanks!

How much ISO do I need?

Ill try to make this short.

My wife and I just moved into our new build house. I am wanting to construct a home studio in the basement that can later be a nice man cave and/or home theater for the next buyers.

I read through Rod Garvais' book, and it seems a little over my head, but there are good points that I could take away from it.
