No JSR I could really hear them flying... Most of my spudguns use 1/2' and 3/4' steel pipes and fittings so i can easily change barrels and chambers in just a few minutes. Usually I use barrels that have greater volume than the chamber - because a 300 psi BANG is something that my ears don't aprove of. 
I could clearly hear buzzing sound of nails flying in the air (I suppose that was something similar to beehive artilery rounds mentioned several times on this forum) as well as steel bolts or 5 cm long pieces of 1 cm thick steel rod ( they were esspecially nosiy possibly becasue of uneven surface and remainds of welds on them )
I don't see any reasonable reason why nobody has encountered that or at least hasn't wrote about that yet
I suppose that there wouldn't be much noise made if I used ball bearings or other smooth projectiles - but anyway it is fun to hear what you shoot.

| In the case of irregular projectiles then yes I'd expect an amount of noise as it cut through the air, for example I remember this instance where Spudinator was impressed by the noise made by the tail of his co2 capsule slugs.

Finally got my hands on the threaded aluminium bit, all it needs now is a lick of paint. Here it is filled and sanded ready for paint:

I'm charging the equivalent of 100 AUD for this one, a bargain for all the love I put into them

| I am going to try to make one of these for my crossman 1377. Will using different pipe sizes have different effects?

| use your brain... a larger volume will increase the silencing effect... thanks for the bump.

| As above, with suppressors there is no substitute for cubic capacity, so make it as big as you're willing to live with for maximum effect.

In that case, I recommend pressing her face firmly against a pillow for effective noise suppression

| will a long or short suppressor with the same volume be more effective?

Longer would be better as it gives the gasses more time to dissipate within the suppressor before the projectile leaves the muzzle.
However, you're usually limited not by volume but by length and width, so make it as long and fat as you can. If you make it square instead of cylindrical, you'll get an almost 30% increase in volume for the same external dimensions, and it will still look cool:
