Can the Vulcan "Ping" be overcome?

The first question is whether the "ping" is the actual hammer slap, or resonance created within the metal by the hammer impacting the valve rod. These are normally two very different sources of noise, but the Vulcan seems to defy isolating exactly what is creating that annoying "ping". It's the loudest I've had on any pcp I've owned.

Although I have heard some anecdotal experience from Vulcan owners that the "ping" quieted down after a thousand shots or so, it doesn't really answer the question of what the actual cause is. Further, given the personal perspective involved with the hearing of "sound" by individuals, one must question whether the "ping" got quieter, or the shooter's brain simply acclimated to the sound and it became less noticeable to the shooter. 

Someone out there must know something about dampening this "neighbor notifier"!

Thoughts, comments, bug-eyed guesses?
 
Airgun sounds don't replicate well at all on Youtube videos. In the past, several individuals who made the LDC's tried to give a comparison, but it just doesn't register on video for technical reasons beyond my personal knowledge. My guess is the same physical law that prevents a ducks "Quack" not to echo comes into play here.

Besides, my head is almost hollow...your brain shrinks when you get as old as I am, so that must be factored in! I do know that the "ping" makes my neighbor's dog bark...if that's any help.

My neighbor's are, under the appropriate protocol for this forum, what one might describe as: "Controlling, and overly observant" of my activities. On another forum, my language is somewhat more colorful and descriptive...actually it's a great deal more colorful, and borders on what some might see as obscene, and most generally used by individuals employed in the naval warfare work force.

I've had my Vulcan since 2nd week of June and probably shot 800 or so pellets down range. I noticed the "ping"...sounds more like the "twang" of a spring to me, however this is my first PCP and I have no other experience to compare it to. It is less noticeable now for whatever reason. I do know that with the location of the hammer and spring in the gun and the fact that my ear is adjacent to that area of the gun when I shoot, along with the fact that it is a mechanical action, how could there not be some noise? For me it is assumed that it is normal. Also was concerned about the gun being "neighbor friendly" with blast and twang so I decide to rig my gun with fishing line and stand down range to the side and shoot it from about 15 yards as an experiment to see what I could hear. I heard no ping or twang and have dismissed that as being an issue for me, the muzzle blast is acceptable as well. I shoot regularly in my back yard, no fencing and my neighbors can be on their back porch 80 to 100 feet away and they say that blast is hardly noticeable to them as well. As to what a dog is barking at......who knows? I can wave at my neighbor's dog and he will bark at the movement...no sound..who would know what a dog is barking at without occupying space in it's brain? I'm planning on doing some video with the fishing line experiment later and will try to post.

Hi guys. The "ping" is actually the resonance of the high pressure air in the air reservoir. When you shoot it lets out some air rapidly and that causes the remaining air to vibrate back and forth in the chamber. Its very common on many pcp guns. Installing a depinger can reduce or eliminate it. There are depingers made for some guns such as Maruaders. It just takes something inserted in the air tube to disrupt the oscillations.
