This is called a "wolf whistle."
There are a couple of spellings used, most particularly for drawn Cartoons.
One is "whoot whoo."
The other is "wheet whoo" (wheet whew) indicating a higher, ascending pitch for the first half of the whistle, and a lower, descending pitch on the second.
A whistle noise is variously rendered as a toot, a wheet, a tweet, a shriek, a shrill, or a blare, depending on the tone and loudness.
In comics, a person making the short, shrill sound was spelled fweet, while the deeper sound of a train boarding whistle was vroo vrooo. The distinction between horns, whistles, and sirens is often unclear.
That is the correct spelling of "whistle" (a sound or a noisemaker, or to make sound or music with the lips).
We all heard a whistle before, but when you are writing something and you want to type or write a whistle sound, it gets you thinking. If I were writing it i would put, WHEWWW, or, PHEWWWWWW. NO A whistle sound makes the sound Whistle
The correct spelling is whistling (making a tonal or musical sound, as from the lips).
The sound a whistle makes is often described as "whoo" or "wee" depending on the pitch and intensity of the sound.
The correct spelling is "whistle."
