dont know if this info helps, but me and a few buddies shoot a couple hundred shots a week. gamo whisper, old beeman r7, and a new beeman with interchangeable barrels (22 and 177). the noise lever between the three is almost identical, but mine is a few hunred feet faster.

Without the use of a decibel meter ... it is difficult to objectively distingish noise intensity.

The Beeman R7 is well known for being quiet.

Even with a good sound level meter, it's not easy to accurately measure an impulse event like a gun shot:

http://www.ishn.com/Articles/Feature...00f932a8c0____

And that's just the start of it, as the article above is mostly focused on the SPL meter. Without an anechoic chamber, it's very difficult to get reliable and repeatable SPL comparisons between firearms, as small variations in the testing environment can make a big difference in the measurements. Also, frequency attenuation over distance is not equal, so while one air rifle at 10 ft may measure quieter than another, at 100 ft this observation might be reversed.

It seems that making noise characterizations beyond the general low, medium and high ratings is tricky and subjective, especially using multiple sources.

Yes, I agree ... all things being relative.
If the provideers of the decibel readings make a good faith effort
to replicate the circumstances for the test(s) in a consistent manner.
Short of a laboratory testing under MIL-STD-1474D standards,
this is is the best that we can expect from the non-professionals conducting
these experiments.

Even though the testers are employing less than ideal methodology.
I, for one, enjoy reading and seeing their results as opposed to nothing else.
That being said, when I post what I consider to be an objective (intrumented)
decibel reading for a particular air gun.
I try to search for a subjective (empirical) observation to correlate the two
findings together.

BSA Lightning XL ... Moderated Springer

Just when I thought I'd figured everything out.
Here comes this compact, mid-powered, reasonably quiet, shrouded, springer carbine.
This small airgun has been on my mind for the last few weeks.
BSA XL
Quote:
First impressions are of a solidly built sporter, but internal and exterior components
have been brought right up to date with some crucial new technological know-how ....

Most noticeable is the 1 inch diameter ‘fixed’ moderator which is 11” long
and almost shrouds the carbine length barrel.
The moderator is actually constructed in three sections
with a pronounced rounded forend and tapered rear section.
The voluminous space inside the moderator provides the XL
with the quietest muzzle report on any spring gun I have tested.
What is more remarkable is that the 12 groove rifled BSA barrel
is only 10 inches long so there is sufficient muzzle blast to tame,
but tame it, it does - very impressive, and one of the reasons I like this model so much.
The moderator also acts as a good muzzle weight and cocking aid.
Lightning XL - Beech

Quote:
Overall you get a sense of solidity in the construction of the new XL.
Indeed with a weight of 6 lbs - and 7.5lbs plus scope and mounts - the
Lightning is fast in the shoulder,
yet its solid feel certainly deadens any movement on firing.
In fact the firing cycle is very smooth, and predictable enough for you
to follow through cleanly on each shot.
This no doubt contributes to the good inherent accuracy.
At 30 yards I set some targets and placed a chronograph 10 feet in front
of the muzzle to record velocities and consistency figures.
I shot several pellet brands and found that the little XL put up very good hunting groups indeed.
5-Shots, 25 yd, .22 caliber
Quote:
The muzzle report was anything but loud,
and I will stick my neck out here and say that the XL’s report
is probably the quietest I have tested, really a very dull thump,
and at 30 yards range it’s inaudible - brilliant.
However, I still have some accuracy and noise concerns.
So, I sent Air Guns of Arizona an email:

Quote:
I'm interested in the BSA Lightning XL
because of the shrouded barrel.
Using the Benjamin Marauder for reference,
how loud/quiet is the XL compared to the Marauder?
Do you have a video info/demo link for the XL?
Is the XL available in the
grade 1 oil finshed walnut stock?
And, I posted a thread at the Yellow Forum:
And, there is a deluxe version ... very nice - aom22.
Lightning XL - Walnut

I bought a used BSA Lightning XL in .22 -- a demo from an air gun trade show. It had a RH composite stock, which I hoped to swap with a friend for a semi-ambi beech stock. I didn't scope it or fire it much for about the first 3 or 4 months I owned it, as I am a lefty. It turned out to be the worst air rifle I have ever owned. First, my efforts to swap stocks were not possible -- the beech stock and the composite stock are not interchangeable. So I sold the air rifle to a friend who kept it a week or two and then returned it to me because it wouldn't group better than 4 inches at 25 yards. It turns out that the barrel shroud would loosen up after cocking the rifle a few dozen times. The grub screw that tightens the shroud is beneath the front sling swivel stud, and it simply isn't stout enough to hold the shroud securely. It appears that for the .22, if the shroud is the least bit loose, the pellet has a tendency to hit the inside of the shroud. Then I found out that the breech face was machined in such a way that unless the pellet was pushed completely into the breech with a pellet seating tool, closing the breech would pinch the pellet skirt and bend it into a "D" shape. Of course, you wouldn't notice this if you simply shut the breech and fired the rifle. So I then had someone with a great deal of skill work on the rifle. The breech end of the bore was chamfered to keep the skirt from being bent after the pellet was inserted, and it still wouldn't group better than 4-inch groups at 25 yards. I suspect the barrel crown may have been to blame, but even though the shroud was loose, it couldn't be removed without permanently damaging the shroud (requiring a replacement shroud or perhaps an entire barrel), which I wasn't willing to pay for. Without replacing the shroud, the barrel couldn't be re-crowned. So, I ended up spending $375 on the rifle, another $100 having someone work on it, and it still wouldn't shoot better than 4-inch groups. I gave the POS air rifle to the gunsmith to use as spare parts. Lesson learned. The BSA Lightning has some very serious design flaws.

I suspect that if your XL had been purchased new ... you would have had some recourse.

Warranty Registration
Quote:
Under our warranty program we will repair faulty guns (and magazines)
free of charge (UK only) providing they are less than 2 years old,
and have failed through faulty materials or workmanship, not "fair wear and tear".
As with all warranties, this applies to guns purchased from new, not second hand,
and we require proof of purchase, such as a copy of the receipt to be sent with the gun.
Wouldn't two of these three make for a fine backyard pair?
.... BSA Lightning XL .......... BSA Ultra Multishot or Ultra Multishot Bull Barrel

Long Range Sparrow Solution

A couple of days ago a thread by Number10GI prompted me to re-think
my sparrow problem and solution.
From short-range scenarios to consider engaging the pesky sparrows at longer range.
Quote:

I'm not too interested in PCP and not at all in C02 models.
Moreover for me, quiet needs to be introduced into the mix.
So, I went-out and measured what presented itself as a realistic shot from a concealed position.
As it turns-out, a 105-foot shot easily stands-out ... maybe, even 120-foot is not out of the question.

And, it dawned on me that Field Target rifle might fill-the-bill for me (and Number10GI) quite nicely.

more so than a best for hunting air rifle.
What immediately came to mind were ...
Beeman HW97 MkIII Air Rifle


Air Arms TX200 Walnut Air Rifle

In terms of quiet ... both of these rifles are running neck-to-neck.

Air Arms TX200 vs the Weihrauch HW97K
Quote:
First up was the 97k ... On the range the Weihrauch felt solid
and well engineered – every inch a thoroughbred.
The actual firing cycle was crisp and more of a refined snap with no spring twang whatsoever.
Accuracy followed, and a ragged cluster measuring just less than half an inch at 35yds
reminded me why the ‘77 had been so dominant back in the ‘80’s.

The TX didn’t disappoint either, and with nylon bearings causing the piston to glide,
a refined, tuned feel is what we have come to expect.
It didn’t like the German pellets though, and they seemed much tighter in the TX barrel,
but over the same 35yds, a competent group of just over half inch was soon on show with JSB pellets.

Making a final choice is the tricky part, but one things for sure – they’re a class act
and capable of taking on any challenge, whether hunting, HFT or even recoil class Field Target.

AirForce Talon SS ... Talon SS With Frame Extender

Recently, I became aware of AirForce Airguns.
I'd not given them much consideration because they are all single-shots.
However, after reading an article in the 01 Feb 2010 issue
of SHOTGUN NEWS ... I became interested in learning more.
Talon SS

Moreover, I learned that AirForce pneumatics came standard with a barrel shroud.
Also, that aftermarket moderators were available as well.
The Talon SS has caught my attention - compact carbine, shrouded barrel, accurate.
Talon SS with Frame Extender

A Talon SS with a small-tank regulated to moderate/consistent velocity that enhances accuracy
and produces a low report further subdued by the addition of a moderator maybe perfect for the backyard.
The net result of the reduced velocity and lower power setting should be a
more urban friendly PCP.
Micro-Meter Spare Tank

Quote:
These tanks allow the rifles to shoot at low to mid level velocities with very low air usage.
This allows the shooter to get approximately a hundred of very consistent, quiet
and accurate low velocity shots for close in target work in the backyard.
Pest control companies who are concerned with over penetration
and property damage when working indoors....
Get a new airgun from AirForce with just a tank change!
Quote:
With the MM tank installed, your SS becomes a 10 foot-pound gun on the highest power setting.
In fact, with the SS, the power wheel doesn't really do much
(exception - if it's set below about No. 6, the shots do vary more in speed).
It shoots .22 Premiers at 560 f.p.s. And, talk about quiet!
It's SUPER-QUIET, with enough power to take out most pests at 25 yards!
If you want more, install your standard SS tank, and you're back in the game.
Stock Talon SS Velocities With 13 Cubic Inch Regulated Tank

Quote:
...using a regulated 13 cubic inch tank from Expert HPA.
The gun is a stock Talon SS with a 12" .177 barrel.
The top hat on the Co2 adapter is set at .045. The PW is at 4.
The regulated tank is set at about 1500 psi.
Starting pressure was 3100 psi down to 1600 psi.
I got 65 shots from a 13ci tank .
I am amazed with these rifles...

The energy is about like an R9 but this gun is much more compact and lighter.
The regulated tank with Co2 adapter is about 7 ounces lighter than a standard talon tank....
I'm thinking ... with an Edge tank and valve/hammer adjusted/modified to generate 750
very consistent feet-per-second using Crosman Premier 7.9 gr pellets.
It maybe possible to achieve 25 to 30 shots before the small capacity reservoir
would need to be refilled.
It should not take many strokes with a hand pump to top-off.
AirForce Airgun Edge Air Tank

What strikes me the most about the Talon SS (for that matter ... all AirForce airguns)
is the design is extremely adaptable.
The concept of interchangeability has been engineered into AirForce products ... Pneumatic Lego's.
Quote:
AirForce Airguns are the most technologically advanced airguns in the world.
... but they are also extremely flexible.
The built in power wheel and interchangeable accessories which include
three barrel lengths, three valve configurations,
and three calibers are sure to provide the right combination for your shooting application...

... now impacting the world of Sporter Class Competition with the
introduction of the EDGE, 3 Position Target rifle.
Many of the components and accessories are cross compatible with the existing line

AirForce Talon SS ... How Quiet

How quiet is an unmodified Talon SS?
According to Paul Capello's of Airgun Reporter ... 106 dbs.
Pyramyd Air Airgun Mall's subjective rating ... same as a Beeman R7:
Quote:
Loudness: 2-Low-Medium
A Talon SS with the addition of an aftermarket shroud has the potential of being quieter.
Talon SS with Micro Tank and Six-Inch Custom Shroud

SURPRISE! A quiet Condor!
Quote:
You cannot hear any muzzle report.
All you hear is the striker hitting the bolt and the valve return spring.

And if you dial it back just a little, you'll get 40 foot-pounds that sound like an R7.

The device that does this wonderful thing is a frame extender that encloses the Condor barrel....

As for how much quieter a Talon SS can be, I doubt it will be any quieter at all.
I think the Condor dialed to lower power (30-40 foot-pounds) is already as
quiet as any pneumatic rifle can be....
Micro-Meter Tank - Summary
Quote:
The MicroMeter valve and tank is perfect for indoor target practice
and pest elimination in places where over-penetration is a concern.

... and the Talon SS is virtually silent with the new valve/tank.

In a Backyard Airgun ... I Think ... Size Matters

In a backyard airgun rifle, I think, size is a factor that matters.
Especially when shooting out of a window into the backyard.
A Beeman R7 (HW30S) maybe the perfect example of small, light, quiet springer
for this purpose.
Similarly, the BSA Ultra Multi Bull Barrel is an almost ideal example
of a small, light, quiet PCP airgun that would make a good window gun.

So, how quiet is the BSA Ultra Bull Barrel?
Jay, Resistance is futile....Expand Thread on Feb 11, 2009 9:22 PM
Top: Beeman R7, Bottom: BSA Ultra Multi Bull Barrel

Quote:
The BSA Ultra .22 Bull Barrel shroud is the bottom rifle.
I placed it next to the top R7 so people can get an idea how small it is at 38".
The one with the factory mod is even smaller at 33"
but this one is quieter, I mean YES, quieter than the R7.
Some more reasonably objective answers.
Quote:

Sometime ago I sent an email to Airguns of Arizona asking:
Quote:
Which air rifle is quieter - Benjamin Marauder or BSA Ultra Multi Bull Barrel?
One final question, is there any other quieter PCP that you would recommend?
This is the response I received:
Quote:
No, for the given power, these two are the quietest.
As to the Ultra, the non-bull barrel version was pretty loud.
The bull barrel shroud really brought it down to the quietest rifle we sold
until the Marauder came out.
Now they are both dead quiet.

We do not have a video showing this, and our tests with decibel meters show us
that you can get the results you want by changing the variables.
If what you are after is our opinion, they are very close in sound.
They are both different pitch, so it would be hard to tell which one is technically quieter.
However, they both sound so close that it is safe to say they're equal.

QUIET: Beeman HW97K vs Air Arms TX200 MkIII

HW97K ... Loudness: 3-Medium
Recently I came across some sound testing information on the TX200MkIII
_and the HW97K that was conducted by the same evaluator.
Essentially, the noise measurements were replicated under the same conditions.
And, some revealing results were compiled.

With this in-mind, it is seemingly evident that the TX200 and HW97K
_are not really head-to-head contenders in terms of noise suppression.
As the TX200 has a shrouded barrel with baffles.
While the U.S. model of the HW97 has a muzzle brake with no internal baffling.
Which is not the case with the European 97K version ... with an integral silencer.

Subjectively ... they may be close, but not quite as close as I had originally concluded
and as instrumented air pressure measurements objectively verify.
Beeman HW97K


Beeman HW97 underlever air rifle - Airgun Reporter Episode #52 ... 102 dbm

Air Arms TX200 MkIII


Air Arms TX200 - AGR Episode #20 ... 86 dbm
Note: See Full Length Video Episode 20 at Pyramyd Air brings Paul Capello's Airgun Reporter

An interesting aspect of decibel measurement, a three db increment results
_in a 10-fold increase in sound pressure.
But, moving on to twenty db there is a 100-fold magnitude change ... geometric progression.
As such, a small decibel increase results a disproportionately greater increase in measurable sound pressure.

Sound Signature: TX200, HW97K, Pro Sport ... Continued

Reference: Most Quiet: TX200 MkIII, HW97K or Pro Sport Expand Thread on Feb 7, 2011 8:56 PM


I was doing some more research on the comparative noise levels
of the Air Arms TX200 MkIII, Weihrauch HW97K and Air Arms Pro Sport.
When I came across these three videos.
Interestingly enough, all initiated by the same evaluator.
For the same purpose.
At the same airgun range.
Under nearly identical circumstances and using the same methodology.



Between the TX200 and the HW97K, the noise levels seem to be indistinguishable.
However, it is not possible to determine whether the HW97K being tested
is a European version versus U.S. import model - most likely ... it is a Euro example.
That is, the muzzle brake is actually an integral silencer containing baffling and packing.

However, in the case of the Pro Sport the sound signature is noticeably different.
As I perceive it .... less intense, not as sharp, not quite as loud.
I realize there may be many variables in-play that may account for difference.

How fortuitous it is to have found these three particular air rifles
so well video documented by the same source.
And most importantly in my case, this is probably the closest I may ever come
to hearing the reports made by all three rifles in consecutive secession.
