EDITOR: Not sure you read the entire article. We state the ASHA standard that the ONE-Shot (spike) damage level is 140db, and that can be exceeded even with suppressors in place. The point is made that, with large cartridge, high-noise-level rifle shots, even with a suppressor of typical noise reduction capability, you can still end up OVER the 140db one-shot threshhold. And, we are told by the team at Thunder Beast Arms, that standardized testing of some other brand’s suppressors showed noise reduction around 25 Db. The point is, that even with a single shot, you could be close to the injury level. The other thing to consider is that at a match you may have non-suppressed rifles going off frequently near you. That may be of no concern to a hunter, but we certainly would advise shooters to test the true noise level of their firearms.
