Levavasseur Whistle
Description
Imagine Taking The Cross Section Of A Standard Referee'S Whistle And The Revolving It About An Axis To Form A Toroidal Shaped Sound Cavity - That'S What Robert Levavasseur Did When He Patented This Whistle In 1956. Word Has It That In Testing A Giant 6Ft Version Of This Type Of Whistle, The Sound Was So Loud That It Ruptured The Internal Tissues Of Levavasseur And Two Of His Colleagues. This Whistle Is A Little Simpler (And Smaller) Than The Version In Levavasseur'S Patent (Http://Www.Google.Com/Patents/Us2755767). While This Version Does Whistle, I'M Sure A Lot Could Be Done To Optimize The Sound. In Any Case, It Will Certainly Grab The Players' Attention Out On The Field!
