Based on the fact that you have never used it, and are discounting my real life experiences to blindly believe what other have told you about this stuff? yes.

Who said I've never used it? I believe lab data. You should too. We are not testing theoretical things here. Sound is one one side of the wall, you measure by frequency the dB on the other side. Measure from 125Hz to 4000Hz. Plot the data, use software to determine the STC contour, and bingo- you have an STC test. ASTM e-90 and e-413. All reproducible.
See, there's absolutely no guessing. It's extremely simple and straightforward. Irrefutable.

and still waiting on this mysterious data "proof" that acoustic insulation makes no difference compared to the cheap pink stuff.....

Ooooo big words! Must be true then.
I don't need any of that nonsense, I am standing next to a wall filled with the stuff! lol I know what it sounded like with the cheap pink stuff in there......I couldn't record over the fan noise and light/pump hum. Now it's silent. I don't need any more proof than that. THAT's irrefutable in my books. Any of my many musician friends that have tried recording in my studio before and after the insulation upgrade would whole-heartedly agree.
I repeatedly keep telling you that there is a profound difference with the Roxul in there vs. the pink stuff, and that there are no variables present that could explain this....same materials, stud spacing, drywall brand and thickness, mudding compound, everything is identical except for the type of insulation between the studs. Despite this, you are so fixed in your views and unwilling to hear anything else that you are basically telling me that either I am a liar, or that my hearing is so badly damaged that the extreme difference in sound transfer between the different mediums is only in my head. When I offer to measure for you, and back this up with real world data, you immediately discount this because I'm not in a $3 million dollar lab even though the difference in sound pressure levels between the two mediums would be far greater than any minimal error introduced by my new and high end pro-sumer audio testing equipment. There is no point arguing with someone that is so close-minded and shut off that they aren't willing to accept or consider anything that conflicts with their pre-established opinions.

And if your musician friends would visit studio building forums (Gearslutz, JohnLSayers, etc) you would see none use mineral fiber my friend. They have read the data.
I gave you the test report numbers IR 761 and IR 693. Google it and compare the data as I already laid out.
I'm thinking that the casual reader of this thread will understand the path. More posts from me won't reveal more. So I'll let you reply with something snarky and you'll have the last word.

Oh, and long-time member of Gearslutz here, but nice try. That's where I learned to acoustically treat both my studio and grow room. Here is a link to a very popular sticky in the "Acoustic Treatment" section of the forums: http://www.gearslutz.com/board/bass-traps-acoustic-panels-foam-etc/54765-treating-studio-rooms-pictures-added.html
Guess what kind of insulation is used in all the DIY acoustic treatment stickies in this forum? Not the pink stuff.......

That's just one sticky. There are many more about building room-within-a-room recording setup, and all use high density acoustic insulation between studs in the isolating walls, not pink stuff. I can post all those too, but don't want to spam and clutter up this thread, there's a lot of them. Also tons of photo journals of professional studio builds......there's no pink insulation to be seen in any of those builds and for good reason.

Here's another quote for you, directly from the highly respected builder Mike Holmes himself, straight from his own website: "I use Roxul batt insulation made from mineral wool especially when I want a fire break and sound barrier."
If it's good enough for Mike Holmes, it's good enough for me He doesn't BS, if he says it works, it works.

I just got a nice message from a long-time member of this site, which reminded me of the whole purpose of this thread: SAFETY. There are plenty of areas where growers can skimp and save a few bucks, but safety is always #1 and the one area to never cut corners is on grow room security. You can cheap out on bulbs, nutes, grow with bag-seed, etc., but when it comes to sound and odor control, every reasonable precaution should be taken. Considering the minimal additional cost of upgrading to specialized soundproofing insulation (~10%), it would be silly for anyone that needs to stay quiet to not spend the extra few bucks and help keep things silent.
This is very much like using a trusted name brand carbon filter vs. a cheap made in China filter.......The cheap filter is $80 cheaper, but only works 50% as well (I know from experience, a mistake I made on my first grow). Is it really worth saving $80 when your safety and freedom is on the line? There are a TON of unnecessary expenditures when it comes to growing, and plenty of ways to save money.....I know, I'm a cheap old bastard myself. Just remember that safety and security is #1 and that an extra $50-80 spent on a brand name filter, or upgraded sound-proofing is a lot cheaper than one phone-call to a lawyer.

That's completely incorrect man. Completely.
Look, you don't feel lab data is worth anything. Groovy.
And I'd spend 10% more on anything that had a proven advantage. It's just that the proof says fiberglass, just so happens it costs less.

My inbox is getting flooded with messages from growers telling me to stop feeding the troll and that they also use upgraded acoustic insulation with positive and noticeable results. That's good enough for me

And no offense, but I'll take Mike Holmes professional opinion on a product that he regularly uses and recommends over yours. He is using it in precisely the same way as any grower would, to reduce sound transfer between rooms.

What law of physics states that having an insulating material of higher density and mass inside of a wall is not going to reduce the amount of sound transfer through the wall? Enlighten us.

Also, last I checked, companies like Owens Corning and Roxul are doing extremely well and their products are flying off the shelves. I really don't think the masses would be paying extra for this stuff if it didn't do what it says that it does/what it is designed to do.

Anyhow, I don't have time today as I'm supposed to be working on a project, but I will conduct the test when I have a spare afternoon and post my results. I'll take pictures of exactly how everything is set up, along with the SPL meter readings at the speaker and directly on the other side of the wall for both the wall insulated with 3" of pink, and the wall insulated with Roxul. I'm tired of repeatedly stating there is a huge difference and you essentially calling me a liar.
