i passed the sound through a hardware equalizer on its way to the speakers yesterday during the first match. a -15db notch filter around 455Hz helped a bit but the tone moves around so it was only a help but a reasonable improvment...
Man that noise was annoying -
Apparently the pitch is B flat below middle C; Middle C is 261 Hz roughly, so a notch around 240Hz might help - and I expect the octave above too for the harmonics (around 480Hz)
The large print giveth and the small print taketh away
