Well actually, a start has been managed. James over at Handbasket made a statement that caused me to ask a question (actually more than one). He saw fit to address it (them) in a blog post and now my curiosity is even greater than before.
Today, I borrowed a decibel meter (Extech Instruments 407730) from work and will use it some time this weekend to see if a revolver (.44 magnum Super Blackhawk) is louder than an autoloader (.44 magnum Desert Eagle Mk VII). I chose these two because they are the only pair that I have that fits the design criteria of the experiment.
1. The firearms must be able to chamber and fire the same ammunition.
2. They must both be of similar size (e.g. medium frame or full size, etc).
3. The meter will be held in my left hand next to the grip and facing me.
4. Six (because the Ruger holds six) rounds will be fired in each firearm.
5. An average for each firearm will be calculated as well as a standard deviation for each population.
Also, the following are true...
a. This means that I will be shooting one-handed. -- So what.
b. The meter is multi-directional. -- It does not matter which way it is facing.
c. I chose this configuration to make the location of the meter firearm specific, not user specific. -- As in, my ears are probably farther away than some folks'.
d. I have not calibrated the meter. -- I am comparing one firearm immediately to another, it does not matter to me.
If anyone has anything to add, I will probably be at it Saturday and am open to suggestions on how to better the experiment. Also, engineer, not artist... so, the pictures will be amateurish at best.
