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.

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.
How does sound travel through the air?
it travels because there are sound waves in the air and they vibrate in your ear.
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.
Is it true that sound waves travel faster through air than through solids?
Through solids because the particles are closer than gas particles.
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
What happens to the air pressure in the bottle when you blow?
Because it sends vibrations through the bottle to make a sound
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.
What is the difference between licking and blowing?
Licking involves using the tongue to contact a surface, while blowing involves expelling air through the mouth. Licking is a form of tasting or exploring with the tongue, while blowing is typically used to produce sound or move objects.
How does a flute prouduse sound?
A flute produces sound by a flow of air blowing through the end of a tube and the keys that are open. The pitch of the sound comes from the length of air that is being allowed through the tube. If more keys are being held down, it will lower the sound. More air has to pass through more distance and therefore creates a deeper sound. If more keys are open it will produce a higher sound. Think of the trombone and piccolo. These instruments work the same way. Trombones have a deeper sound because of how long the air chambers are. Piccolos are higher because the air only has a short way to pass through.
How come blowing through a pipe makes a sound?
Brass instruments involve the blowing of air into a mouthpiece. The vibrations of the lips against the mouthpiece produce a range of frequencies. ... This forces the air inside of the column into resonance vibrations. The result of resonance is always a big vibration - that is, a loud sound.
How does the french horn make its sound?
by making it blowing its aif to push it through
Why do chimes belong to the percussion family?
Because for it to produce its sound, you have to strike it. It also produces sound through the vibration of the metal keys or the instrument as a whole. This is the reason a Glockenspiel can be considered as a Percussion Instrument.
What can a flute be compared to?
Well a flute can be compared to a recorder because they are both played by blowing air out of your mouth to produce sound. The difference is just that a flute is blown ACROSS and a recorder is blown INTO.
How do musical instumnets produce sound?
Musical instruments are divided into families according to the way they produce sounds. String instruments produce sounds by plucking or bowing strings. Woodwind and brass instruments produce sound by blowing air into them. Sounds from percussion instruments are produced by striking on them.
Why does a conch shell make that weird noise when you blow in it?
The sound produced when blowing into a conch shell is due to resonance. The shape of the shell acts as a natural amplifier, enhancing the sound of the vibrations created by your breath. This phenomenon is similar to blowing across the top of a bottle to produce a similar sound.
Do you blow into any brass instruments?
No not really, you buzz into the mouthpiece to create a sound. Blowing into a brass instrument like you would for a woodwind instrument that has a reed will not produce any sound.
