...In the development process, the focus was on keeping the production and operation as straightforward as possible. When fired without a silencer, the sound pressure level can reach 140-150 dB, while with the silencer in place, it is reduced to 120 dB.

In my testing it dropped the DB level from 117 to 77 on my OLD Radio Shack DB meter (which to be honest might have measured the impact clink on the suppressed test). The accuracy didn't seem to be affected, and the velocity seemed to increase by an...

Initially, it registered between 69-71 dB, but after implementing this design, it dropped to 59-61 dB. Although I'm not certain if the app is calibrated correctly since I just downloaded it for these measurements, I'm pleased with the results, and...

Using "dB Meter" on my iPhone to measure noise at approximately 30-40cm, I obtained before-values of 69 - 71 dB, whereas the after-measurements yielded results between 59 - 61 dB. While it's unclear if the app is calibrated accurately, given that I...

... approximately 111 dB on average. * With a cap in place, the amplifier reaches an average of 104 dB. * When combined with the silencer section and a cap, the overall noise level drops to 84 dB - adding thin foam further reduces this to around 78 dB.

Here are my findings: Normal operating conditions: 70 Db Standard foot + Cover_cof: 65 Db My Cof design alone: 59 Db My Cof with Cover_Cof: 54 Db Please note that these values are approximate, and I'll strive to conduct more precise measurements in...
