I agree with Zradix, The second bow was the quietest and the noise seemed more from the rest/side plate than from the string. A quiter rest and that bow would be silent.

sinew
bamboo
glass

I could hear either arrow slap, arm guard slap, or both on all three, which made it tough to distinguish between them.

Other than the slap/click, they all sounded pretty quiet.

For bows with no string silencers, I thought they all did well.  The second was probably best but with some silencers they would really be whisper quiet.  What was the weight of the arrows?

I honestly didnt hear a whole bunch of difference. They all sounded pretty darn quiet to me, I think your safe to leave the string silencers off any one of those bows.

Mudd, the next time I am in town for a couple of days we can get together and I have access to a high dollar decimeter and we can find out for sure.

Mudd! I turned the speakers up on the iPad ,then turned the speakers up on my decimeters(hearing aids) and my thoughts are for bow #2 to being the quietest.  Great job on the vedio! Maxx

What Drewsbow said!  Purtiest one too!!

Mudd - I think the sinew/osage bow was easily the quietest.

Maybe I'm full of it here, but it looked like sinew/osage bow had a shorter length and higher brace height.  Am I wrong?  That could be the reason why the sinew/osage is quieter.  

On the bows I've built, higher brace = quieter and shorter length + higher brace = quietest.

Second one.......  

Glass bow had a noticeable "twang." The 2 wood bows are where it's at.

The sinew backed bow was the quietest, followed by the bamboo backed bow and the glass backed one came in last. The glass backed bow wasn't bad, especially since it didn't have string silencers.

Roy I didn't hear a whole lot of difference between the three. I'm going to agree with Rick in that I think what you can hear on the video is coming from either your armguard or the arrow going across the strike plate/rest.

Exactly what Zradix said.  Thanks for letting us see those fine bows!

That was tough to tell. I'm interested, those bows sure are nice!!

Sinew backed quiet but like someone said, with silencers and tuned arrows all would be DEADLY quiet

2nd was quietest for sure  

#2 sinew backed  ... then #1, and last is #3

Nice video Mudd, the Osage royal sounded the quietest to me then the sinew backed.

I vote you get rid of the trash barrel bow holder.

I cringed, and I just knew as soon as I saw it that one of your bows would end up on the ground. Cool video none the less. Glen

They are all very quiet. That said the sinew backed osage bow was definately the quietest, with the glass bow and bamboo backed osage bow just about tying for second.
