I wondered a few years ago if there is some harmonic signature to a well struck shot ...
Obviously materials and clubhead speed are important...but the extra special something seems to be universal whether it is range ball ot ProV...
Is that certain sonic characeristic measurable?
According to TGM Book, a (Dual) Horizontal Hinge provides the perfect strike because of the same line of compression from impact to ball separation. Because the golf ball can only deform (Flow) in two directions when perfectly struck, the ball remains thicker on the line of compression. I can only guess that this is what causes the deeper resonating pitch "crack" when all of the space is squeezed from such a large section of the ball. Or is it caused by the return flow?
But does that mean that Hitters don't typically make that sound, because Layback Flows that minuscule amount away from the Line of Compression?

2-A RESILIENCE The response of the ball to different applications of force is the factor that determines how force must be applied to produce a desired result.
Resilience is the key factor in ball response. Neither a rock on a spoonful of clay will act the same as a golf ball. The ball is subjected to a violent deforming compression. The ball is actually distorted, not compressed – except for reduction of one dimension. Rubber is incompressible. Trapped air bubbles can be compressed – but not the rubber itself – it flows. It flows in two directions – but acts like a solid in the third. This third direction is the direction of the compressing force. The momentum of the violent return of flow after impact also distorts the ball by exceeding the normal dimension of the compressed point. The “kick” given to the ball by this action is an important factor in ball response. Roll of the ball on the face of an inclined striker does not account for all the action produced by such an impact, especially in imparting spin to the ball. When the direction of the compressing force does not pass exactly through the center of the ball, a spin will be imparted to the ball. It will rotate on the plane of a line drawn form the line of compression to a parallel center line.
According to TGM Book, a (Duel) Horizontal Hinge provides the perfect strike because of the same line of compression from impact to ball separation. Because the golf ball can only deform (Flow) in two directions when perfectly struck, the ball remains thicker on the line of compression. I can only guess that this is what causes the deeper resonating pitch "crack" when all of the space is squeezed from such a large section of the ball. Or is it caused by the return flow?

Daryl,
I'm not learned enough to answer your questions, but I find them very interesting. In my opinion, from where I am in my journey as a hitter, I am making a totally different sound during the line of compression than I have for years. I am loving it. Perhaps I am not fitting the exact mold of a "hitter" though. I have a feeling that I am still employing some horizontal hinge action. My feeling of "hitting" may just be a better use of the magic of the right forearm on the back stroke. It may be easy to confuse the two motions for rookies like me.
Trying to find a way to get to the swamp...

Daryl, all, is the leakage just Layback or is it Clubface rotation as well? I dunno.
Ive been wondering about the implications of 2-C-1 to the hitters angled hinge action as well. The book illustrates Horizontal and Vertical but not Angled.
If the Line of Compression ( Angular Force as an equal to Linear Force via a point of contact between clubface and ball that remains intact and rotates on plane at separation) holds true only for Horizontal Hinging then that renders Angled less powerful, no? Does this mean that Luke could drive it 400 yards with a Thrust and a Horizontal Hinge? Does Luke do this I wonder? Or is the compression leakage associated with Angled within an acceptable margin given the obvious directional superiority.
What did Arnie do on the first hole at Cherry Hills again? I mean after he hitched up his pants, you idiot.

Ya know, I still get the same compression sound when I draw or fade the ball. So I think that there must be some room in the amount of leakage or the kind of leakage. I'll need to study it further, but I don't know if a Hitting Stroke has the kind of leakage we're talking about. Angled Hinging still has a solid straight line of compression and impact and separation points are the same as well. So does Vertical Hinging and so does the cut shot. So I assume that the compression sound is present in any strike with these characteristics.
Back to the Book.

2-C-0 LINEAR FORCE The ball will respond to non-linear (angular) force exactly the same as to linear forces only if the application produce forces equally linear to the ball but not necessarily linear to anything external to the ball.
Briefly stated, it is necessary to find a way to compress the ball through a particular point along a particular line, and maintain this compression through the same particular point along this same particular line straight line, through the entire arc of the Impact Interval, and with geometrical precision for consistent control. Study 2-K and 2-N.
You know the Scotty Cameron thing about feel really being a sound and how when its your cooking it never tastes as good? Well Im wondering if we really hear our own shots properly? Maybe if we were blind folded or something. Hey doesn't Karrie Web have a blind golf instructor? He just listens to the sound of impact.
