    I've watched many badminton matches, and in some of them smashes sound like the crack of a bullwhip or a gunshot, whereas in others smashes make a weak "whfft" sound. What causes this difference? Is it the particular brand of shuttlecocks that a tournament decides to use?

    anything that can affect sound:
    temperature, pressure, size/shape of hall, strings, string tension, racket, shuttle, contact angle, racket head speed.

    For example, the "crack of a bullwhip sound" can be heard in this match, while a less sexy smash sound can be found in this match, which sounds more like a muffled pop.

    I think it's just where the mics are placed. If by side of court, then it'll be sharper.

    Does anyone know this string where you just swing the racquet like in a smash way and there's like a huge whoosh sound :0

    All my rackets make a loud swoosh sound when I just swing them without hitting the birdie.

    Zymax 65. I don't think it matters what string if you are just swinging. But when hitting a real shuttle, different strings make different sounds at a given tension.

    Yeah it doesn't really matter but when it comes into contact with the strings, it makes this same
    Sound this guy at my school had it and I really liked it, I currently have zymax 67 at 25 lbs

    The LCW -- Kenichi Tago was a prime example of the whipping sound. The sounds of the shuttle hitting the strings was so exquisitely beautiful it almost made me cry at times.

    Maybe it was due to them using Z's. :)

    LCW Z Force and Tago Z Speed.
    And it was crazy how Tago strings at higher tension than LCW because you can hear the difference in pitch at strike.

    I thought I was hearing things....good that you think that Tago had a higher tension as well!

    Are the head sizes the same? A smaller head will sound higher pitched.

    From the ZSP thread elsewhere, the head frame size is smaller, so it is bound to have a higher tension, when pulled with the same pounds and force.

    Generally, the smash should have higher pitch with
    - thinner strings and
    - smaller head size, that is a smaller string area when you use the same pull.


    Hope you can sound engineer the next racket according to your taste.

    Yes, ZSPD is a tad smaller than ZF, but only most noticeably at the bottom where it's shorter by 3-4mm. Along with the bright neon orange colour, the compact frame makes it look like a toy racket, imho. :p

    I'll try to get a frequency reading of LCW and Tago's hits when I get home tonite.

    There are only 3 factors that affect pitch or frequency of a string.
    1. tension
    2. length
    3. linear density (ie. lighter, thinner)

    If you replace the length with the SQR(AREA), because you may to account for the "woven pattern" of applied strings of a real racket, not just the length of one long string, then you may get a more accurate calculation.

    Informed by some Physics Department, University of Sydney, Sydney, Australia, in July 2006.
