"snakengrass"
"Dartagnan"I've always wondered why my Wildcat, with an LDC, is much quieter when shooting in the middle of a field when I was just shooting next a building and I thought was loud. Even with the barrel facing 90 degrees away from the building, the blast seem to echo off the wall behind me and make it sound loud. Has anyone else noticed that?
What you are referring to, isn't really volume. It's sound pressure. The reason it sounds louder inside vs the middle of the field is because there is more space to absorb and dissipate the pressure caused by the firing.
Instead of air, think about water to visualize. if you took a golf ball and dropped it into a coffee cup of water from 12" above, it would splash everywhere and make a mess, and you wouldn't see any "ripples". If you took that same golf ball and dropped it into a calm lake from 12", it would make much less of a disruption because the waves that are created have the ability to lessen over distance (you would see the ripples).
Back to air, in a confined space, just like the water - sound creates waves, the higher the frequency (pitch) of the sound, means that there are more cycles (measured in hertz). If there isn't enough space for the length of the wave (based on the frequency), it causes the "perceived" loudness.
Golf ball in coffee cup = shooting in a confined space (boom)
Golf ball in lake = shooting in a field (tick)
