Why are whistles so loud?
Air enters the whistle at one end. As the air reaches the other, closed end, all the air molecules "pile up" on top of each other and cause a high-pressure region. The air escapes out the little hole in the end, making the noise you hear. The frequency of the sound is dependent on the length of the whistle.
Why are whistles high pitched?
Whistle has higher pitch because the air columns in the whistle vibrate more number of times than the stretched membrane in the case of drums , so whistle has higher pitch ( REMEMBER Pitch matters upon frequency not loudness .)

What Are The Best Ways To Spell A Whistle Sound?
There are many great choices for the onomatopoeic sounds of a whistle. Some of the best include:
Fweet
Let’s start with “fweet,” which is the best version we can come up with. It’s also common to see this version in comic books.
Phweeee
You might also use “Phweeee” in much the same way. The number of “E’s” you use at the end of the word is based on the length of the whistle sound.
Phooweet
Again, we’re using that repeated “E” formation in the word to highlight the whistling sound with “phooweet.”
Whooee-uueet
This one gets a little more specific than the ones we’ve mentioned above. The long and drawn-out “whooee-uueet” works best when trying to get an animal’s attention, like your pet dog.
What is a whistle?
A whistle is a device that makes sound from blowing air. The physical theory of the sound-making process is an example of the application of the science of fluid dynamics. Knowledge of the geometry, dimensions and fluid properties can allow prediction of the properties of the whistle.
What is thermal whistle?
However, when amplification can occur, a small variation can grow and have important influence on the sound field created. The most well known thermal whistle is the Rijke tube, a vertical tube with a heated gauze material placed inside.
How to describe whistle feedback?
Feedback in whistles is nonlinear. Because of the nonlinearity, it is possible to have more than one frequency at a given flow rate. The difference depends on whether the flow rate is achieved by increasing the flow or by decreasing the flow. The possibility of multiple states is called a stage and is shown schematically in the figure on the right. As the flow speed increases ( Reynolds number, Re) the frequency slowly climbs (nearly constant Strouhal number, St) but then the frequency jumps up abruptly to a higher stage. As the flow speed is later decreased, the frequency slowly decreases, but then jumps down abruptly to a lower stage. This pattern is called a hysteresis loop .
How can whistles be unified?
Whistles come in all shapes and sizes, but their operation can be unified through the concepts of dynamic and geometric similarity. Nature knows nothing of the specific measurement systems we use; it cares only about ratios between the various forces, time scales, and the several dimensions. To compare them, we need to take into account the established ratios that are relevant to whistle operation.
What happens when a subsonic jet impinges on a cavity?
When a subsonic jet impinges on a cavity, jet instability becomes part of the feedback loop as with the hole tone. When a supersonic jet impinges on a cavity, shock wave instability becomes part of the feedback loop.
What is a sound wave that generates sound through momentum?
Whistles that generate sound through fluctuations of momentum or a force exerted on the surrounding medium are called dipole-like sources. The figure on the right is example of a small rigid sphere that is moving back and forth in a given direction. This results in a non-uniform sound field. The sound power can be expressed as
What is Sondhauss tube?
The Sondhauss tube is one of the early thermal tone generators; it was discovered in the glass-blowing industry. A bulb with hot air is connected to one end of a tube that is at room temperature. When the cold tube is blown, tube acoustic oscillations occur. It was discussed by Baron Rayleigh in his "Theory of Sound". This device is not considered a true whistle, since the oscillations decay as the temperatures equalize.

What is the sound of a whistle?
The sound of a whistle is closer to a pure tone (like a sinusoidal wave), which means that it has one major partial called “fundamental” and several other partials much smaller than its fundamental (a perfect pure tone has only one partial). In human language, the tonal sounds are the vowels, but all of them are composed by several partials. So, there is no vowel that can quite resemble the sound of a whistle. Consonants are even more distant as they are not tones (quasi period sounds) and are composed by an even bigger amount of dynamic changing small partials.
Why does a whistle sound like a whistle?
I think it sounds like a whistle because of the vowel, ee. The reason a whistle sounds like this is because when the air enters a whistle, it curls around. It has to break through an earlier part of the air flow because part of the air is going out the top slit of the whistle.
