Taipan Mutant/Veteran .22 .25 shorty std DB sound test
I ran across some hard too find sound info, testing the Taipan 22 short, 25 short, & 25. standard back to back. Looks like in the three shot tests.
Thought I’d pass it along. :biggrinn:
May be help for some one, thinking of what Taipan too get.
The 22. Taipan short the sound DB was 90db, 91db, & 83db I’ve seen it tested in the 80db range.
The 25. Taipan short was 85db, 88db, & 82db thats pretty good for a short barrel 25. pushing over 40 fpe.
Then the 25. Taipan standard was 86db, 91db, & 87db.
What are you guys thoughts on this. 🙄
Here is a few more videos too look at:

How many shots are getting, at 40 before it falls off the reg? 🙄
Using Benjamin domes, 27.8grain. at about 40fpe which is just about 805fps, regulated range is about 800-820fps.
So just done shooting and it goes 38 shots then increases about 10 to 20fps at a max of 840fps for about 7shoots then drops down to under 800fps by 50shots. So basically 50 usable shoots. 250bar to 150bar gets 30shots, by 50shots it is about 100bars or just under. So it looks like the regulator could be adjusted down a little to get more shots within the regulated range possibly 50 regulated shots…..not bad I would say.

Isn’t the comparison of the .25 Shorty and Standard a little tainted? Don’t you have the Standard tuned to 55 fpe? I’d like to here both at 45 fpe.

yeah not the same fpe, the std. at 55fpe and shorty at 45fpe both sound about the same maybe a tad quieter on the std. If set at 45fpe on the std. it will be quiet like the .22 shorty at 27fpe. The sound/report does sound different
been playing around with the shorty .25 and find that at 40fpe it is quieter and doesn’t sound like it is wasting air. At above 40fpe you can hear and kinda see a puff of wasted air. Also looking a how much I have to turn the HST anything above 40fpe it needs more turning while 40fpe and below there seems to be a much less adjustment needed to make changes in fpe. I’m gonna have to do a shot count, check spread and SD. From the initial impressions it seems 40fpe has the smallest SD compared to above and a little below. Think that the reg. set and the barrel length at 40fpe might be best.

Thanks for your response, Foxback. Actually, I had been communicating with DaBinChe on many of his youtube vids in the past as well as the veteran vids. I was quite sure he stated that he adjusted the Standard to 55. I may be wrong. However, that is how I remember the vid. Ergo, my initial question. I would expect the Standard to be quieter as well. I just wanted opinions from experiences.

He was merely sound testing his guns, from the factory the way they came.
He really wasn’t putting one up again the other.
There is not alot of sound testing, on these guns.
If he tuned both the 25 short & the 25 standard too 45 fpe.
Then the 25. standard, would be more quite.
It has a longer barrel, & a longer shroud with a lot more baffels. :biggrinn:
Let’s not take DaBinChe test out of context. :confusedn:

I feel you too, Rowdy. I clearly understand that a truly emperically accurate measurement would require a sound proof environment and the shots would have to be measured over a frequency spectrum, while recording several controlled samples, analyzed and statistically calculated.
I just wanted any input, given people repeatedly opine on the subject. Not looking for a peer reviewed thesis. Just opinions from folks lucky enough to have both guns. I’m rolling with my Mutant Shorty .22 til the wheels fall off. However, I am interested in info on the .25.

This is the age old question here, if a tree fell in the woods but there was no one or anything to hear it; did it make a sound?
Long story short here, is NO! It did make the wave forms that are everywhere all the time, there just has to be someone or something to absorb it and dephyfer to make what we understand as noise…
Now we apply this to the shorty, standard and might as well throw in a long, all tuned to the same pellet and same speed. They are all three the same energy level.
This will show you why its only a db meter that can compare these three on their merits here. Because any live thing that makes sense of wave forms to noise, hear the notes differently. One of us hears ythings better than another and vice versa…
So that out of the way, leaves us with the three different barrel lengths which is going to produce a different sound note on their own. Therefore, I might here one note better than another, you might here the other note better. People or anything living would not make a good judge…
Hence the db meter and its scale!!! I will all get down to the individual and the note he can here better or more importantly, the note he may not hear so well.
The loud factor is a relative term, unless you hear all notes the same and equal quality, then that can tell you which is louder, don’t mean it’s louder to us or not, as we all hear things differently…
Shorter barrels in general are louder to us, as in case pistols, but you add the ldc to these different length barrels the notes are going to be way different from one to the next. The machine, will only be able to truly mark them as which is louder.

Dear Cros…
PCP sound is a very relative thing. What you hear depends on your location in relation to the source of sound, ambient noise, age, health, hearing acuity, brain function, and personal experience of connecting certain tones and frequencies.
On a personal note, a video is a terrible means to judge sound. The microphone is a major factor, because there are microphones and then there are microphones. A microphone is nothing more than a mechanical ear. Quality ranges from ultra high definition to barely adequate. Most video camera mikes are in the “barely adequate” to “adequate range”.
The long story short…everyone perceives sound different. The only way you will ever be able to determine “loud” is to do the experiment yourself.

Hoot,
I feel you on that call. However, speaking from a pedestrian acoustician perspective, I wonder what the relative perceived difference between the short and standard .25, may be, given the guns barrel and shroud attributes, set at the same fpe? Was it significant, given all things you so well articulated?
:hoot:

Well…there I was, walking my dog at 8:00 am and bumping into various neighbors. I know all about old people, loss of brain function, forgetfulness, and de-conditioning and such…so I make certain I get plenty of exercise when it’s early and still cool. I always stop to chat with the widowed neighbor ladies.
After my dog walk, I got home and realized my fly was unzipped all the way. I apparently forgot to check it when I got dressed. So I figure there I am with my dick hanging out for all to see, and no one says squat to me about it???
Oh well, it ended OK, because after I got home I tried to take a leak, (at my age that’s not a guaranteed thing!) Well, I up and pissed my pants, before it dawned on me I had also put my underwear on backwards, so the pee-pee opening was in the rear, and not the front!
None of the neighbor ladies got to see all three inches of my corn-fed, USDA prime pork!!!
Hell I guess I was just born lucky!!!! AND…does anyone remember what the topic of this thread was? I can’t recall…

Nice find on your Taipan 25.
Looks like the 25 shorty is flexible little rig.
Keep us posted on your tune, what you find out. :biggrinn:
