Quoted:
That noise level comparison chart could use some work. Showing a suppressed .22 rifle as being louder than a emergency vehicle siren? WTF? Are they comparing a .22 next to your ear versus the siren at a mile away? Impulse noises (gunshots) generally sound quieter to the human ear than prolonged noises (like a siren) due to the short span of time that your ears are exposed to the sound. A siren will meter quieter than the suppressed 22LR gunshot, which is why it's positioned in that spot on the chart. The same goes for the jackhammer and the .223 rifle. A human ear will perceive the jackhammer to be louder, but the gunshot will meter higher. |

Even though it is right about absolute noise levels, these figures lead people to erroneously believe that a suppressed 22 sounds louder and causes more hearing damage than a siren. Both of these conclusions are dead wrong and are fairly implied from an advertisement promoting the hearing-damage-prevention benefit of silencers. |
