Hmm a suitable studio might just be the problem. I know a couple people with small ones that are great for recording but are nothing more than acoustically reinforced closets. We might have to rent a space large enough to give paint some airtime.

I have a buddy who is an acoustics engineer in a research lab.

He likes cool projects, I will ask him about setting up an accurate test.

Sweet, doc! That's what I'm saying. Somebody on here must have or know someone with these resources.

I don't want to say that it's arbitrary... But my involvement honestly is.

In the past, I've been very careful to not make any specific claims about my designs so far. This is actually tiring because I'm excited about the the project! You don't have to look far back in this thread to a single instance of just implying a claim, getting called out on it, inviting a direct attack to my professionalism, my integrity, and the raw value that I bring to the community.

That sucks... I don't get a lot of reward for sticking my neck out too far around here. So third party testing is number one on my list before I'm spending a ton to move forward.

Please note that I don't speak for Ty or his involvement. This type of project literally takes mega-hours and big dollars. If you look back in this thread, or could see our emails... He's a huge contributor and deserves the acknowledgement.
Thank you for the props

This has been a joint effort, involving more than just Alpha and I. Unfortunately, my swiss cheesed brain won't tell me who... But if you read back through the thread, you can figure it out

Freaking AWESOME!

Having done some serious testing, I might suggest that using an Eigen barrel as the core might be the best solution. 8" of control bore and loads of small diameter porting make it very quiet. If you throw an old Taso cover over it, it makes a DM almost silent. You can actually hear the bolt sliding in the bore!

That would be awesome, I don't think I know Any lab types, just entertainment industry sound engineers. They have the expertise, just not the space. I did work at a recording studio for a bit but I doubt we would be trying to rent something for this project.

I just talked with my buddy.
He will need a weeks notice to get the stuff allocated

We are going to test outdoors under field conditions and indoors in my basement.

So I know that it's been around two and a half months since anyone posted in this, but what with renewed updates on the Typhoon thread, I wanted to ask something, and not clutter up Alpha's sale thread. Sorry if I am naive about this.

Specifically with the Typhoon raincover, it is basically matched to the Inception back. Would it be worthwhile to use a smaller insert in the Inception to get the better efficiency that underboring delivers, while still using this raincover? Or would it be better to use a larger bore, so overboring, to get the most out of the sound deadening qualities?

I've never compared the two. But I've been going with "less air is better". The Typhoon r3 is .690 diameter.

I've been using them with a .679 insert on the theory that better FPS efficiency means that I can drop the pressure to get the same speed. Which means that there's less air to divert away.
