Mating Yelps

[nickmarch]

Have any of you tried mating yelps?  After reading about mating helps I read some scientific and university studies about a turkeys hearing.  Somehow I managed to make a mating yelp call that is at the volume and frequency stated in one of the studies.

Turkey's do not hear what we hear.  What sounds great to you might sound horrible to them or they might not hear it at all!  

Volume is decibles (dB).  Tone frequency is hertz (Hz)  Decible Sound Pressure Level is (dB SPL)

The range of frequencies that a turkey with good hearing can hear is 290 Hz to 5,250 Hz. 
Humans with good hearing hear a range from 20 Hz to 20,000 Hz. 

Both humans and turkeys hearing frequency range declines with age. 

The optimum dB SPL is15.43 Most calls are louder than that and above the pain threshold.

The best frequency is 2,000 Hz

If you are using calls with a frequency higher than 5,250 Hz the turkeys cant hear it!  They may feel pressure on their ear but they won't hear it.  The only response could be a shock.  You wouldn't be calling them but you could be shocking them. 

Numerous Crystal, glass, aluminum, ceramic and slate calls are higher than 5,250 Hz and above 15.43 dB SPL. Some turkeys calling can call at frequencies that turkeys cant hear.

Maybe that is a reason why you get toms gobbling and going away from you?  You aren't calling them you are shocking them!

But does she shake her tail feathers?

Human hearing changes too...

It seems that Brenda no longer hears my mateing yelps

I watched a hen cluck a Tom in to mate and it was the worst sound I’ve ever heard. She got her man....  I previously posted my story but every time he walked away from her to me, she clucked him right back.

Obviously hen pecked

The pic shows what frequencies humans hear (dashed line) and what turkeys hear.  The left side is decibels.  60 hz is about the volume of a human talking.  Most if not all calls on the market are to loud.

I get my best response from box calls. I use mouth calls when the toms are getting close so I have both hands free to shoot.

Turkeys hearing is different than ours.  What we hear and what they hear are different. 

Turkeys have a columella, which speeds up the vibrations to the part of the brain that recognizes sound. This quick progression means that birds literally hear faster than us. While we hear sounds in bytes about 1/20 of a second long, birds discriminate up to 1/200 of a second. That gives turkeys the ability to hear shorter notes, where one note to us equals ten notes to them. 

Your yelps might sound spot on to you but not to the birds.

I think my wife might have that. whenever I try to get out unheard or unseen she always seems to catch met.

What do you mean the best frequency is 2.00 Hz....but above that you said a Turkey w good hearing can hear from 290 Hz to 5,250 Hz?

Is there a device that can measure our calling...there are times I know birds are there and I’m probably piercing their skulls w calls

Good catch! Thats a typo I fixed it.  I said 2hz it should have been 2,000hz or 2 khz.

There are apps that measure the frequency range of sounds.   Search your phone app store for...

Spectrum Analyzer

I have seen numerous posts about turkey hunters that get toms gobbling but they don't come in.  Their calls are probably causing a shock gobble because of the range of their call.  

Or that the toms hangs out of range and won't come in.  That could be frequency range and/or volume.  They say the reason is that the hen is supposed to go to the Tom.  Thats BS to me.  If that was true toms wouldnt get near hen decoys but they do!

Ol girl got some rhythm & doesn’t miss a beat!!

So much for the theory to not over call.  

I've always called to the extent that others would say that I over call but I'm successful!

I started feeding them the other day due to the lack of acorns.  I'll feed them throughout the winter.   I add garlic and Cheyenne pepper to keep the deer from eating it.  I also add minerals and fat.
