In the simplest case, when the velocity of an airstream passing over a sharp edge exceeds about 1m/sec, then turbulence is developed in the airstream. This we hear as a broad-band (random) noise. The airstream is no longer laminar.
This is the basis of several Musical Instruments, such as the Flute.
Each time the velocity of the air is doubled, the noise goes up by a 7th power law! An increase of 24dB for each doubling of velocity. This is an important limiting factor in the design of industrial and domestic fans.
As far as the pure tone whistle that you may produce with a straw or the top of a bottle, the random noise produced by the turbulence serves to excite the natural resonance of the receptacle. Thus the notes of a Pan Pipe also.

How does sound travel through the air?
it travels because there are sound waves in the air and they vibrate in your ear.
Why can light travel through space but sound cannot?
sound is produced by vibration, i.e. when any thing start vibration then it produces sound. for example when a tunnig fork is hit on rubber pad its prongs starts vibration with difinit frequency ad hence produce sound. similarly when the strings of a gittar is dirturbed its starts vibration and hence produces sound. sound required a material medium for their journey, sound can not pass through vaccume because sound waves are mechanical waves.
Is sound everything?
Yes because the air makes vibrations that make a sound. no matter what it is it makes a sound because of the vibrations.
How a burning match stick produce sound when it dipped in water?
The burning match stick produces a sound because of the heat its flames are producing. The snuffing of the fire produces a tiny bit of steam, which make the hissing sound.
What kinds of insternents are there?
Instruments can be broadly categorized into four main families: strings, woodwinds, brass, and percussion. String instruments, like violins and guitars, produce sound through vibrating strings; woodwinds, such as flutes and clarinets, create sound by air vibrating within tubes; brass instruments, like trumpets and trombones, use lip vibration against a mouthpiece; and percussion instruments, such as drums and tambourines, generate sound through striking or shaking. Additionally, there are electronic instruments that use technology to produce sound.
Blowing through a starw can produce a sound because?
blowing through a straw,air touches the walls of the straw and makes the it vibrate and as it is a light body it makessound
Is a trombone classified as a wind instrument?
Yes, a trombone is classified as a wind instrument because it is played by blowing air through a mouthpiece to produce sound.
Is the trombone considered a wind instrument?
Yes, the trombone is considered a wind instrument because it is played by blowing air through a mouthpiece to produce sound.
How does blowing through a pipe produce a sound?
Blowing through a pipe, such as a flute or a recorder, causes the air inside the pipe to vibrate. The vibration creates sound waves that travel through the air, producing the sound you hear. The pitch of the sound can be changed by altering the length or shape of the pipe.
What are the different types of blowing instruments and how do they produce sound?
There are three main types of blowing instruments: brass, woodwind, and free reed. Brass instruments, like trumpets and trombones, produce sound by vibrating the player's lips against a mouthpiece. Woodwind instruments, such as flutes and clarinets, create sound by blowing air across a reed or through a mouthpiece. Free reed instruments, like harmonicas and accordions, make sound by air passing through a reed that vibrates.
Does blowing through a shorter straw make a higher pitch than blowing through a long straw?
Blowing through a shorter straw creates a higher pitch sound because the shorter length of the straw produces a higher frequency vibration upon blowing. This is due to the shorter distance the air needs to travel through the straw in order to create sound waves.
What are the different types of woodwind instruments, such as the clarinet, and how do they produce sound?
Woodwind instruments include the clarinet, flute, saxophone, and oboe. They produce sound by blowing air through a mouthpiece or reed, causing vibrations in the instrument's body. The vibrations create sound waves that resonate and produce music.
Why does blowing through a longer straw make a deeper sound?
Blowing through a longer straw creates a deeper sound because the longer straw allows for a longer column of air to vibrate. The longer column of air vibrates at a lower frequency, producing a deeper sound.
What is a musical sound by blowing air through the lips?
A musical sound produced by blowing air through the lips is called a "buzzing" sound. It is commonly used in brass instruments like the trumpet or trombone to create sound.
What is the sound that the keyword "ac" makes, which resembles the gentle rustling of wind blowing through the trees?
The sound of the keyword "ac" is a soft and gentle rustling, similar to the sound of wind blowing through trees.
How do pan flutes work and produce sound?
Pan flutes work by blowing air across the top of the tubes, which creates vibrations. These vibrations produce sound waves that travel through the tubes and are amplified, creating the distinct tones of the pan flute.
What instrumental family does the clarinet belong to?
The woodwind family, on account of the old clarinets being made of wood, and blowing wind through the instrument to produce sound.
