How do the All-Weather Safety whistles make so much noise?
Back to
the Top
About a
hundred years ago a professor of physics named Hemholtz devised a box
that would take sound waves. Depending on the size of the box, it would either
muffle the noise or increase the sound. This is like throwing a tennis ball
in a room. If the room is very large the tennis ball will simply roll to a
stop. If the room is very very small the tennis ball will be stifled and not
go anywhere but if the room is just the right size the tennis ball will bounce
off the walls and rebound all over the place. Helmholtz found that a box with
a noise maker inside would either increase the sound waves or decrease them.
This principle of sound augmentation and amplification was never applied to
whistles or alarms until Dr. Howard Wright invented the Storm Whistles in
1988.
Do the All-Weather Safety whistles really work underwater and how does that
work? Back to

Yes. the All-Weather Safety whistles really does work underwater. As
a matter of fact I invented the All-Weather whistle for just that reason.
When I was just 14 years old I built the first Storm whistle so that my
friends and I could play Marko-Polo (an
underwater tag game). To make the standard whistles work underwater I encased
the whistle in a plastic box. When the box filled with air the whistle
worked. After further testing I proceeded to make the plastic box smaller
and smaller until he came to understand that the sound producing area of a
whistles was a small 5mm x 5mm area over the whistle exit opening.
The whistle is used by dive clubs to organize multidiver events and to
signal a
buddy while underwater. The ability of the whistle to work when wet is even
more
important for boaters and rescue individuals. Standard whistles do not work
when they are wet. If you fall off a boat or are lost as sea a whistle that
works when soaking wet is critical. This is why Navy Rescue boats, hundreds
of thousands of boaters and search and rescue teams across the world demand
the power and waterproof nature of the Storm and Windstorm whistles.
How loud is the Storm whistle?
Back to the Top
The loudness of the Storm whistle was derived in a sound proof chamber
by a
research team at the Institute for the Deaf in St. Louis Missouri. the
Decibel reading
varied between 118 and 120 dB.
We compared the loudness of the Storm whistle, Windstorm whistle and a
number of our competitors whistles. The Storm whistle was nearly twice as
loud as any
other whistle. The Windstorm whistle was not quite as loud as the Storm but
was clearly
louder than any of the competitors.
Below I have a graph illustrating the loudness of the all-weather
whistles Vs the
competitors at a determined flow rate and at a given distance from the
receiver.
What is the difference between the Storm whistle and the Windstorm whistle
Back to the Top
The All-Weather Safety Whistles comes in two styles,
The Storm and the Windstorm All-Weather Safety Whistles.
The Storm is the original all-weather safety whistle and is manufactured at
its exact dimensions in order to produce the most noise energy possible. It is
manufactured in order that it can be heard through walls, through glass and
through water. The Storm whistle is the loudest whistle in the world and can
be heard over a 1/4 of a mile through trees and over a 1/2 mile over water.
Over the years however, a number of our customers desired an all-weather
whistle that was a little more compact. They wanted a whistle that was a
little smaller to fit into a hand bag, on keys, or pocket on a life preserver
but still demanded a very loud whistle. For that reason we developed the
smaller and more compact Windstorm safety whistle. Smaller, the Windstorm is
the second loudest whistle in the world. Second only to the par famous Storm
All-Weather Safety Whistle.
The Storm whistle is the most powerful whistle in the world, easy to hold
and easy to hear, it is used by Safety and Rescue teams around the world. The
Windstorm whistle is the more compact and sleek version of the Storm whistle.
Both whistles have waterproof capabilities, tremendous power and sleek design.
Together the Storm and windstorm whistle make the greatest whistles in the
world.
When asked how I use the Storm vs the Windstorm whistles I answer, As a Boy
Scout leader I use the Storm whistle while making sure that the scouts have a
Windstorm.

Back to the Top
As shown below the Storm and Windstorm whistles come in three colors ,
Safety Orange, Safely Yellow and Black.
How are
the Storm and Windstorm whistles packaged?
Back to the Top
The Storm and Windstorm whistles are packaged on full color blister cards,
in a plastic bag with a header called a poly bag, or without any packaging at
all.
From this web site [Internet Advertising's wind-storm-whistles.com]
whistles are sent on a full color blister card unless prior arrangements are
made.
Can
the whistles be printed for my school or business?
