Thread: String Tension Test By Sound

any extra long? D600's, w10's, w11's...or also 'standard' 675mm?
what are you doing to those poor rackets...
Never had that problem so far.. Though that w9A I have feels more flexible than it was when I first picked it up .. breaking it is another thing..

I asked Halim (Haryanto Ho) the same question, "Halim, why do I break so many rackets and how can I avoid it?"
His reply was, "Dan, too much [panda ] power. No racket is going to last you."
I have consulted with other coaches and the conclusion was unanimous, that I am not optimizing the transfer of power I generate into the shuttle. As a result, it's taken out on the racket. The reason why pros don't break rackets like I do is because they are much more efficient at transferring power. Once I learn to transfer the power more effectively, I'll break less rackets and hit harder.
This is already starting to work as I'm breaking half as many rackets as before.

A question for the panda:
My racquets were re-strung yesterday.
I chose Yonex BG-65Ti (which, like the Ashaway Micro Power, is 0.70mm).
All the racquets were strung at 27 lbs.
While playing your video, I tested my Ti-10 racquets.
Surprisingly, my 27 lbs sounds exactly like your 29/30
Worse, your racquets have been used for a while after stringing.
Given that the gauge is the same, why would this happen?
Could it be that my stringer has wrongly calibrated his machine?
I'm beginning to WorryALot!

so, if your stringers equipment is calibrated, your tension should drop about 2-3lbs after a session or two...
pretty plausible if you ask me.. Freshly strung sounds tighter than slightly used...
play with them once, then recheck, it's probably of by 1lbs or so..nothing to worry about...

Instead of saying high pitch, it does not really mean much. For us who know music, please list the "note", it is much more meaningful for reference for tension.

I think string thickness (more precisely linear density) and length of string between the ends of the frame would alter the pitch of the sound, since the frequency of the sound depends on the tension of the string, its linear density, and its length.
Maybe badminton strings are pretty similar in thickness and frames are similar in diameter so those may be negligible.
I think in general the sound is a rough indication of tension though.

Craziness isn't and hasn't ever been my forte, but what the heck!
I just tested the panda's ting-ting-ting-ting against my piano
25/26 is almost exactly C
27/28 is close to C-Sharp
29/30 is almost exactly D
31/32 is close to D-Sharp
PS: Strumming would've given a better sound
This hit-hit-hit-hit creates an unusual timbre

I'm wondering if anybody has ever tried to make a tune out of badminton string "tings" (what I am saying - this is BC: of COURSE you have!).
Something simple to start with. The 5-note "Pentium" theme, for example.
