You will note that I think using an oscilloscope, (to measure the sound wave) would be a good thing. I recall starting out in the benchrest shooting game in the late 50s - the days of Harvey Donaldson, Bob Hart, Mike Walker and other BR shooters - there were a lot of "what's that?" and "huh?" in the conversations. As a result, discussions on shooting and hunting ran on and on - as everything was repeated several times for the story to make it around the table. We used to stuff used cigarette filters in our ears to muffle the noise on the shooting line. I still own the first set of ear muffs I bought in the early 60s.
Now I ask "what's that you said?" and "huh?" a lot.
