Do you have a video showing the db sound with factory ones first, and then with these ones?That will help, because there is no point to get it without first see what is the report's change.Thank you.
So you developed a product for specific rifle, and are selling it without first having any concrete data results to show?Thanks anyway for your response.
I installed the QE Stak Pak on my Hatsan Flash today. I shot two different pellets. One that chronographs @ 1013 fps and the other is too fast to register on my FX wireless chrony, so 1099+ fps, and almost certainly supersonic from the crack. I'm sure it is exaggerated in my basement, but it does crack.According to the dB Meter Pro app on my phone, the actual decibels were not reduced in my basement shooting area. However, the apparent sound when shooting the 1013 fps pellet outdoors was noticeably changed/ reduced. Previously it had enough of a 'pop' to it to make me uncomfortable ( neighbor-wise ) shooting in my backyard. Velocity was hanging in the same range, after installation, for a short 5 shot string.I have no report on the effect to accuracy. My indoor range is only seven yards. I did not shoot the fast pellet outdoors, in broad daylight, because I didn't trust it to not still have the audible crack and alert the neighbors. I'll try one or two around sundown when most people will be indoors.
...... the sound change is more than just dB change and involved tonal changes, it is almost impossible for video capture devices to properly capture the changes. I have made several videos where dB changes were captured using smartphone applications or stand-alone sound meters but the results are only for reference as the testing equipment or app is not a calibrated instrument.I typically rely on users to share their impressions and or experiences.
