In spite of the prefex I'm not a student, just a very curious person with more than 9 lives to waste :)
I have a Golden Retriever but she's never been used as a gun dog. She is terified of loud noises like thunder and fireworks, even a distant firecracker will have her shaking for hours. We have a gun range about 2 miles away and while the sound is a little quieter than the firecracker last night she doesn't seem to pay any attention to it. Though I'm not certain, I went to the range about a year ago to renew my range permit and I think there was some shooting then but I just can't be sure. It would be unusual if there weren't.
Last night I was thinking about why one sound would bother and another would not. My only thought is in the pitch. I've noticed with my own ears that fireworks and thunder sounds more like a boom where gun shots (smaller bore vs shotgun) make more of a snap. I'm assuming because it contains more high frequence sound. So my questions (and there are a few) all related to gunshots not lightning or fireworks:

I'm assuming because it contains more high frequence sound. So my questions (and there are a few) all related to gunshots not lightning or fireworks:
- How much of the sound is from the explosion and how much from the projectile exceeding 1100 ft/sec.?
- If it's primarily the explosion than does the barrel act as a high pass filter?
- If so than is the barrel length to diamater acting as the z?
- If you lengthen the barrel (assuming the same mussel velocity, I know it can't) will you raise the frequence cut off, ie is the length to diamater ratio determing the cutoff frequence?
- If it's primarily the explosion than does the barrel act as a high pass filter?
