https://www.youtube.com/watch?v=EE-z8U11GG4 Man I want to produce that fast whip sound when smashing. It seems to be an indicator of a good and powerful smash. Any tips? I been trying to use forearm pronation but always seem too weak.
Factors that influence the sound when smashing (in no particular order): 1) string tension 2) string thickness 3) speed of the shuttle being hit 4) hitting the sweet spot And yes, the sound is a good indicator of a good clean hit. But the type of shuttle is also a factor. I'm saying this because it says on your profile that you play with plastic shuttles. You will never get that kind of sound (from the pros of the video) with a plastic shuttle, regardless of the other factors.
The only factor to consider is technique and practice. In other words you can't buy that attribute.... it has to be earned.
It's not just only power of the forearm pronation, but explosive acceleration. Think of using your arm as a whip.
Usually the problem is more to the mistiming of the wrist movement (so that it really hits the shuttle before it is too late or too early)
you can try this way. Imagine throwing a stone to hit some fruit on the tree while you swing your racket. feel the timing when the shuttle leave the string bed. in time, you should able to produce a crisp clear effortlessly. Crisp powerful clear skills will assist a lot on smashing. Master this one first to reduce miss hit. then imagine throwing a stone to hit somebody you hate (a politician perhaps) real hard. you will swing better on your smashes. use to tell this story to my friend who try to learn badminton. equipment comes after skills i believe. one of my friend, he played for our college team. and he can produce powerful smashes from almost any racket with tension as low as 20lbs(default factory string)
The higher the tension/thinner the string the more it will sound like the pro players, if you have the right technique.
I wouldn't be too hung up on the sound although it is a good indicator. Concentrate on the points raised above and the quality of your smash. There are other influences in play too, the acoustics of the hall, the temperature and humidity can also affect the way the shot sounds. Also as we are hearing the sound via a microphone and recording it is a little different to hearing it in person.
The swish sound in the video is more pronounced when the player in standing nearest to the camera, and negligible when he is on the far side, so I probably wouldn't place too much emphasis on achieving that specific sound. As R20190 mentioned, the mic may pick up specific frequencies that emphasise that swish. A strike with nice clean contact has its own happy sound - good feedback that you have struck it well.
Swiff sound is one of my parameter to try a racquet, I compared it strung and unstrung. Sound of high freq being a parameter how hard the racquet to be part of hard hiiter player. More factors that included this parameter is The shaft (slim or original shaft), frame type (aerodymanic, air cut), and string thickness (if strung). Try to swing over and over, created much power to try smashing techniques and hearing the swiff sound clearly. Maybe my tips can help your instuition..
being a moderate player, the whiff sound = speed. if i can't win the game, at least the sound + speed will intimidate them.
Recently I have experimented a lot with different strings and tensions. I can agree with thinner string + higher tension = sharper sound. But playing with super thin string on high tension might not be the best for your playstyle! So far for me 0.66mm string (Nanogy98) on 12kg seems to be the best fit, thinner string or more tension makes me break strings way too often because of mishits...
