Just got my Arche!I wanted to report my bounce test. Blade weighs 83.2g. I'm getting: 1331Hz on the FH side, and 1336Hz on the BH size. The difference gets bigger if I use a larger window size for the analysis: with a 8192 size window (same audio file, about 8x times larger window) I get peaks at 1327hz on FH, and 1338hz on BH. That's with 1 minute's worth of bounces on each side.
I'm not sure whether this difference between FH and BH is big enough to be significant - or whether it's due to factors I can't control for. Would be curious to know what results other people get on bounce tests with BH vs FH. |
In my case I got 1317 Hz on either side (I was lazy and recorded only 3 series of bounces each).
Even on Nexy's objective measurement scales, the FH and BH sides are essentially rated the same both in terms of elasticity and perceived hardness.
Nexy's position is that the bounce test and their measurements measure impact perpendicular to the blade face, and in this case the blade behaves as a whole, regardless of which side hits the ball. So it makes sense that the measurements are the same or very close.
They say the difference becomes noticeable when the impact is tangential, i.e. when spinning the ball, because then the top ply closer to the ball has a more active role, whereas the top ply on the other side of the racket is less involved.
I cannot directly confirm this, because I play with different rubbers on FH and BH.
If you can (I mean any tester), please put
same rubbers on FH and BH, and let me know if you perceive any difference.
