Talk:Firearms and Explosive Weapons

Sorry if this upsets anyone but I had to delete the words 'non-audible' from the description of 9mm ammunition. Non-audible suggests that they cannot be heard, and this is most definitely not true. Most ammunition is fired at supersonic speed, which means there is the little matter of the noise made as it breaks the sound barrier. Some 9mm ammunition can be found which is rated as subsonic, but these still clock in with a volume around 120 decibels, only 10 dB below the amount recognised as the pain threshold for noise. A good suppressor will lower the noise made by firearms by around 40 dB, but this would still put the subsonic rounds at about 80 dB - about the same as a garbage disposal or food blender. Non-audible? You must be joking. 86.167.198.167 22:59, May 14, 2012 (UTC)
