DIY moderator test

I tested these four moderators today. I didn't spend too much time collecting data but I think I got enough to figure out what I needed to know.

The actual noise level for the unmoderated rifle is on the far right on the graph. It is very loud about like a subsonic .22.

The one on the left in the image is version one of the prototype that I am working on. The one next to it is a Tatsu and the one next to that is a Tonto. The carbon fiber one on the far right is one I bought years ago for a BSA Lonestar I had. I don't recall the vendor.

I got the following results.

The chart says it all pretty much. I am happy with the prototype's performance. I've never tried to make anything like that before so, I figure, not bad for a first effort. The Tanto is an impressive value for the money and really does a fine job with that Condor.

I have a version two of the prototype in work now and will try to test it soon.

Note on the graph: The bar represents the spread of noise levels measured one standard deviation above and below the average for each moderator. Statistically 2/3 of all measured values should fall on the blue line for each of the devices.
