I have a question that some of you might be able to help me with. I probably already know the answer, but here goes. Is there a simple, inexpensive way to measure the loudness of a firearm from a distance of about 50 yards? I’m not talking about precise db measurements, just comparing the report of say a .22 and a .38 revolver and being able to see the results on some sort of graph. Would any of the sound recording programs available for computers do this?
I would like to develop a quiet, accurate load for about 25 feet that I can shoot in a K38 revolver without disturbing anyone. I have a safe, semi-indoor place to shoot, but firearms noise tends to bother folks. I have used plastic, rubber, and wax bullets with primers for power, but I would like something a little better. I have also used a muffler tube like the army developed and it works pretty good but it is cumbersome.
I know that sound level measurement is very complex, especially with impulse noise like that of a firearm. I would just like to have a better way to compare the noise levels of different loads without having to yell at a friend “how did that one sound?”
If you have any insights on this, I would like to hear them. Thanks a lot.

Interesting...
I am no expert on the subject, but I would think that you would be able to compare different loads. Just make sure automatic gain control, level control or normalization is turned off.
A sound meter would be much better and are available for under $100. I know Radio Shack has one. Do a web search and I'm sure you will find more.

I hate to say it, but the answer is NO.
The problem is that firearms produce a very sharp report - a very fast rise in the pressure curve. Ordinary sound meters are not sensitive enough to pick this up accurately. The suppressor design community is using high-end pressure transducers (try the subguns.com bullettin boards for details) for this sort of thing.

Thanks for the replies. That is kind of what I thought. After doing some reading I see it takes some sophisticated equipment to compare that type of impulse noise. Thanks anyway.
