To me having the can on the gun no matter what size is inconvenient since you can't holster it till the can is removed. You might as well go for the better sound reduction. I have read that sound is twice as loud for every 3db. </div></div>
You read incorrectly. For every 3db the sound is increased slightly, but the energy used to increase that sound is doubled. Everyone pretty much can hear a 3db gain. Many hear a 1.5 db gain. Some can hear 1 db gain. The power necessary to increase the sound by 3 db is doubled. The sound itself is increased very little. Read up on electronics and physics.</div></div>
or you can read a recent work and get it right...
Is 10 dB or 6 dB sound level change for a doubling or halving of the loudness (volume) correct?
About the connection between sound level and loudness, there are various theories. Widely accepted is still the theory of psycho-acoustic pioneer Stanley Smith Stevens, indicating that the doubling or halving of the sensation of loudness corresponds to a level difference of 10 dB. <span style="font-weight: bold"><span style="text-decoration: underline">Recent research</span></span> by Richard M. Warren, on the other hand leads to a level difference of only 6 dB. *) This means that a double sound pressure corresponds to a double loudness. The psychologist John G. Neuhoff found that our hearing is more sensitive to rising levels of sound as to falling levels. That is for the same sound level difference the change of loudness from quiet to loud is stronger than from loud to quiet. It is suggested that the sone scale of loudness reflects the influence of known experimental biases and hence does not represent a fundamental relation between stimulus and sensation.
You will hear 3 dB as <span style="font-weight: bold">significantly</span> louder, at least 50% louder ( or HALF again as loud) and some research suggests more.
Neither are hearing safe no matter what anyone tells you. If its over 88 dB wear protection, there are a good number of people having their high end frequencies torn to shreds by confused science and quackery. A .45 auto (ball ammo) is approx 154, now subtract from that the dubious number of your choice, lets say your left with the full monty 123 dB number (wet, cool can). SO what else is 123 dB? Er, well, a chainsaw is 115, or Sandblasting is approx. 118, Threshold of pain? 125. Riveter? 126. Time allowed under OSHA per 24 hours at 125? seconds. Run that can dry and your at 133 (at friggin' least!) and where are you..what? speak up.
