  • The Storm whistle is twice as loud as any other mouth-blown whistle in the world
  • With a standard whistle, nonproductive high frequency (over 5000 hertz) and nonproductive low frequency (below 2000 hertz) sounds are created.
  • Because of the patented harmonic chamber that is unique to the Storm whistle, these high and low frequency sounds are recycled and focused into our extremely loud single 3150 hertz frequency of double the standard amplitude.
  • Used by U.S. Coast Guard, Washington, D.C. , New York Police Department & many more
  • Be heard ! Colour may vary
