  I&apos;ve watched a ton of his videos. 3 years ago, i bit the bullet and built 2 4&apos;x4&apos; cabinets using his activated carbon technology. I found a video of one of his customers showing the building process of a cabinet they made, and found a seller on ebay that sells carbon pellets in bullk for air purifiers. Cost me about $500 for 250lb of carbon. I was amazed by the low frequency control... my room is 11x12 with 8 ft ceilings, so its far from perfect, but those cabinets did a crazy amount in a small space. Like, they work down to around 40hz, which is totally fine for me, considering room size. I don&apos;t know if his services are worth it for most people, but trying some of his technology in my space made a drastic difference.

  What&apos;s the purpose of the double wall? To control low frequencies from penetrating your walls. The whole idea is that the more mass in the wall system you have along with decoupling the inner wall from the outer wall to prevent transmission then you can eliminate those low frequencies from either entering you control room from outside or having those low frequencies escaping out of your studio into spaces where you don&apos;t want them. Mass and decoupled wall structures is how it&apos;s done. More of each is always better. The trade-offs are available space and cost.

  This was really entertaining, and I think you hit the nail on the head: budget makes a lot of decisions for us, and the double wall technique works enough for most of us. I’m almost done building a studio in my basement and I’m getting more than enough isolation for my needs. I can use my guitar amp at 70-75dB when the family is sleeping and no one hears me. I haven’t even sealed off the studio doors yet, or installed the flooring! (Concrete slab for now) Like you said, it’s all the little details like HVAC and air sealing that makes the difference. I’m excited to see how much isolation I’ll get when the doors are fully sealed and the flooring is installed with insulated subfloor.

  Nice topic!!! Dennis is the ultimate Guru of sound physics! I&apos;ve been watching his channel for years and love his techniques. Unfortunately, His technology is far beyond most of our scope. However, that particular video made me rethink my personal space. My room is down to the stud and I will probably be trying a budget friendly sandwich 😅 &nbsp;Regardless, I appreciate both of your knowledge within this crazy vibration transmission space.

  So I caught this video just as I&apos;m starting my drum room build. &nbsp;I&apos;m a loud drummer, I need all the soundproofing I can get. &nbsp;So I called Acoustic Fields and Dennis answered the phone. Ha! &nbsp;We chatted. &nbsp;He&apos;s awesome. &nbsp;He guaranties 90 STC on frequencies from 40hz to all of it. &nbsp;He gave me a quick ball park price at around $20,000 for my 12x12 x 8&apos; room in a detached garage.. &nbsp;This is using his design and me building it DIY. &nbsp;He said the wall thickness would be the same as my &quot;room with in a room&quot; design with better outcomes. Actually he said my design will fail.. &nbsp;I&apos;m building a completely decoupled wall and ceiling system at 11 inches thick for about $6-7k. &nbsp;But IDK? &nbsp;I&apos;m gonna cross my fingers and go with my design. we&apos;ll see. &nbsp;If I had the budget I&apos;d go with Dennis.

  Great video! I have a question though. Why is it called a “spring” does it spring the noise or sound into mass and dim it? Does it suck up the air and propel it? Why is it called a spring and what does it do?

  For my hometheater, I was thinking of using rockwool between joists and studs, and install a double layer of 5/8s with green glue, I am also planning to seal outlets and use a solid wood door....however, I have a air vent and forced air vent in the room....would this defeat everything I am doing to &quot;soundproof&quot; my hometheater?

  I need help soundproofing. I have concrete wall on 3 sides so I was wonderin if I should connect stud and insulation on the walls and add air gap with furring channel or give a inch air gap make studs separate of concrete walls with insulation then layer of ply

  Just vacuum the air out from between the walls, no more spring.<br><br>Thermos studio, good for temperature insulation too! 🤣

  Im just making a cinema room now, I thought we had it nailed when you taught the double drywall technique….. did you now just imply it doesn’t really work for those low bass movie sounds? 😮
