Longbow / Recurve Sound Comparison

[RickBarbee]

Still working on a way to capture the sound into two apps at the same time.
No sound, but the meter don't lie.

If anyone knows of a way to force the microphone to work with two apps at the same time, I'd sure like to know.

Can't help with the microphone issue, sorry.

How hard do you work to make your recurve quiet?

Not very hard on the recurve.

Most of it is just having a good string, good tuning, and a moderately heavy arrow ( I like to be between 9 & 10 gpp), but I do add string silencers (my own yarn puffs), and limb saver vibrations dampeners on the limbs just outside the riser butts on the belly side of the limbs. On one piece recurves I put the dampeners at the limb fades on the belly side.

So, both very quiet and less than 1 decibel of difference between the two. Neat.

Set up similar to what I set up but I promise you the sound difference of my two bows the recurve is louder/sharper. Both 55@28. Same string, silencers, limb dampners etc. Same arrow both bows, about 9.2gpp. I don't know. But neither one is "loud" compared to many I seen. Or my compound for that matter.

Things to think about:

(1) String to limb contact creates noise:

The string contacts the limbs of the recurve well beyond where it terminates in the string notches of the limbs.

The string on the longbow only makes contact in the string notches of the limbs.

Quietness advantage - Longbow

(2) While not in every case, higher energy usually creates more noise:

The recurve has somewhere in the vicinity of 25% more stored & delivered energy, than the longbow. This recurve likely more than that.

Quietness advantage - Longbow

(3) Arrow weight/GPP will increase noise as it gets lighter, and decrease noise as it gets heavier:

In this test the longbow was using 0.35 gpp (roughly 25 grains) more arrow weight in gpp difference.

Quietness advantage - Longbow

Yet, there was only 0.6 DB noise level increase for the recurve over the longbow. That very well could be only due to the difference in GPP arrow weight.

What say Ye?

My recurve and longbow are, though untested, about the same. Just my longbow makes a longbow thump. My recurve makes a recurve twang. Same arrows for both. I do have to run larger string silencers and pad the limbs on the recurve to achieve this though. The recurve noise and vibration are also more sensitive to small creeps in brace height and release flaws. I think that more than anything, more energy more noise.

[DRT]

I use recurve wraps as well. Honestly some of the noise difference is probably just pitch.

One more thing to think about:

String angle on the fingers.

A longbow, especially one in lengths of 66" or more (this one is 68") lessens the string angle, and yields a smoother loose of the string, making it quieter.

Even a longbow of the same length as a recurve has less string angle on the fingers.

Quietness advantage - Longbow

Yours is a static limb recurve correct?

Yours is a static limb recurve correct?

Gary

Yes, and I do believe that makes some difference / results in a quieter shot.

I intend to do some more testing to include my statics against full working recurves. I have both in the same length, and same draw weight (within a couple pounds).

I'll be interested in seeing the difference, and I know others are as well.

I have always said:

I don’t know if one is any louder than the other, but longbows go “thud” and recurves go “twang”.

I just like the thud of a longbow better than the twang of a recurve!!!

Just lose 80 percent of your hearing in one ear and they all sound really good lol.

I don't recommend it.[emoji44]
