Sound Is Energy\n\nHome\nThe Energy\nBrass\nPercussion\nString\nWoodwind\nSuper Quiz\n\n \n\nTo enjoy all of our sound files download "RealPlayer" for free from the Internet.\nDid you know?\n\nHorn and woodwind players kiss their instruments? Watch one, next time, and you’ll see why! The position of the player’s mouth around the reed or mouthpiece is called "embouchure" which comes from the French word "boucher" meaning "to kiss".\n\nEnergy In The Air: How Sound Is Made \n\nCRASH! BANG! Did you hear that sound? It was made by air vibrating. The same is true for sounds made by musical instruments. The difference between NOISE and MUSIC is that musical sounds are organized into patterns that have pitch and rhythm. Noise is just random, disorganized sounds. Sounds are made and travel in the same way whether they are musical sounds or noise.\n\nA musical sound is called a tone, and is produced by air vibrating a certain number of times per second. These vibrations are called waves. These sound waves must be contained in some way so that the performer can control the loudness, quality of the tone, and how long it plays. Most musical instruments have a reed, a string, or some other device that creates sound waves when moved. Sounds are different because of harmonics, which are higher and quieter sounds mixed in. They are not heard separately, but add to the tone of the sound, making an oboe sound different from a trumpet or drum.\n\nThe number of times that a sound wave vibrates in a second is called its frequency. Scientists even have a name for how they measure the frequency of sounds. They measure it in cycles and call it hertz. High notes have a higher frequency than lower notes and this changes their shape. Different types of sound waves have different shapes. Look at these images to see what sound waves "look" like.\n\n\nFor the rest go to the site below.

If you can measure the *frequency*, you know the wavelength.\n(As the wavelength is just the frequency divided by the speed of sound.)  I found a calculator that does this for you:\nhttp://www.sengpielaudio.com/calculator-wavelength.htm\n\nIdeally you would get an oscilloscope to measure the frequency.\n\nIf you don't have access to one, if you have a guitar tuner, you could measure the frequency (the tuner will tell you the pitch, say A#, and you can look up the frequency of that pitch in a music book).\n\nOr if you have a bunch of tuning forks or a pitch pipe, you could get an approximation.\n\nIf you have an ocilloscope, don't forget to get the precise speed of sound at your elevation (sound travels a bit faster at sea level, than if you live in, say, Denver).  (Note that the calculator link above gives you a place to enter the speed of sound where you live.)  If you're using a guitar tuner or tuning forks, they are only approximations anyway, so the exact speed of sound for your elevation won't make a difference.  \n\nP.S.  I found a reference to a sound analyzer you can get for your computer!  The software is free, but it needs a soundcard in your computer (which you probably have).  It uses the information from a microphone in your computer to give you the frequency and wavelength of the musical note.  It's kinda cheating if this is for a science-fair project ... but maybe this is what you want.\nhttp://www.relisoft.com/Freeware/freq.html

Sound is made up of compression waves propagated through air when these waves hit your ear they are what we call sound.  when they come in contact with a surface, depending on the makeup of the surface, energy can be absorbed or resonated or both.  If the energy resonates the material and no loss/absorption occurs then the sound will be the same on both sides of the surface (think of a membrane wrapped tightly over an opening like a drum, or ear drum for that matter which has little absorption qualities).  Because a naked/unmodified ceiling is rigid, it has resonant properties and the sound will permeate through the ceiling with some loss. Different surfaces have different amounts of loss/absorption, and some surfaces have excellent absorption qualities, such as off the shelf acoustical tiles, usually hung on a suspended ceiling (mostly because these materials have poor structural qualities and cant be built into the floor).  \nWhen in place the majority of sound energy is absorbed in these tiles and very little is resonated through them, thus sound insulation is achieved.  \nOne thing that needs to be pointed out is that ears are extremely sensitive over a wide range of sound powers, so much so that sound reduction is usually measured in decibels which is powers of 10. The interesting thing is that in the moderate sound power situations the brain has a hard time telling the difference between 10's of decibels, unless there is a point of reference.  And what is meant by this is suppose you are playing the drums in your basement and someone upstairs complains,  you add a false ceiling with some accoustic tiles and continue to play, and still you get complaints you may have lowered the sound that your neigbor recieves by many tens of decibels, but yet their brain still picks out the drums from their quiet environment.  At this point the solution is to go out and buy them something that makes noise, like a hepa-filter or fan, and give it to your neighbor and some how convince them that having it on all the times extends thier life.  Now and only now will the neighbor stop complaining about the noise.

Although we can't hear the sound the sun makes in a usual way from earth -- since sound can't travel through the vacuum of space -- we can make measurements of how portions of the sun are rising and falling and deduce what vibrations must be going through the sun because of this.  These vibrations are equivalent to sound, though at a much lower frequency.  For instance, middle C on a musical instrument vibrates the air back and forth 256 times a second.  For one vibration on the sun to go back and forth typically takes 5 minutes.\n\nSo the vibrations are at a frequency far below what human hearing could pick up, but if you multiply the frequencies to bring them into the range of what we can hear, the site below lets us listen to what the sun would then sound like.

ur ques is incomplete. in a microphone it gets converted to electrical energy

No. Sound is a waveform of energy that travels from particle to particle. When there's no particles the wave stops. Kind of like waves of the sea don't continue on land.\n\nBut - if you have a planet with atmosphere that's thick enough you'd get sound.

To measure the mass-energy of a region of space and say it's zero (with no uncertainty) you'd have to measure it for infinite time.  So if you only measure it for a finite time, you can only say the energy is less that a certain (non-zero) amount.  This is logically equivalent to saying that during that small time the energy could be any value between zero and that amount.  And there are actually measurements that reveal physical effects of this fluctuating energy, for example, the Casimir Effect.

I'll give you a little visual guide here.  \n\nOk lets think of a piece of string.  One guy stands on the end of it and he is moving it up and down and making the string look like a wave.  Now the particles in this string are only moving up and down..(there is no forward movement)  \n  The "wave" which is accually the energy that the person on one end is supplying IS moving.  The energy moves from one end of the string to the other .. and yes some reflects back.  The particles of this string don't move at all.

Sound is the biological interpretation of compression waves in the air. No biology, no sound.

Yes there is sound. Don't confuse sound with 'hearing'. The speed of sound is given in ft/sec, varying with what it moves through.. There is no factor there for 'hearing'. If you turn on a flashlight at night and a beam is created, but there is no one there to 'see' it, light is still emitted; the beam is certainly there. It's the same for sound. Sound is a compresson/rarifraction wave moving through a medium. The wave is there, detected or not. Or take the case of radio electromagnetic waves. The wave is certainly propagated, even if no radios are turned on.

This is essentially a question of definitions, i.e. how you define sound or noise. \n\nHere are the two basic answers. \n\nYes \n\nA noise is a sound and a sound is a set of vibrating molecules referred to as sound waves. If a tree falls in the forest and makes a sound, it makes molecular vibrations, or sound waves, whether any human ear drum is around to sense them or not. So yes, it makes a noise. A person hearing it is irrelevant to the being of the sound. A person hearing it is only relevant to human consciousness of the sound. \n\nAnother argument for this viewpoint is based on theology. God observes the entire universe. \n\nNo \n\nIf a tree falls, and no one is around to hear it, it does not make a noise by definition. What is noise? What is sound? One must make sure to look at this question not from such a skewed view point to realize that he or she is being misled. From an early stage in our lives, through modern science, it is FACT that sound waves are processed in our brains, thus if we are not near the sound it is just an assumption that it does make a noise. \n\nSound travels through our ears, into the canal, and into the brain to allow for it to be processed by the brain, allowing for us to differentiate due to experiences that yes, it is that particular noise. However, one would not know the sound to be that way if they cannot imagine the situation. Thus, a human being or another entity must be present to absorb the vibrations, waves, etc in order to process the information. \n\nSome take this further and claim that the whole universe does not really exist until it is observed.

Your question lacks specification so that the answers may clearly give you results according to your expectations. any object can make sound for sound is a wave of energy which is released due to a collision of some sort. sound can be created by speakers which uses a permanent magnet with a coil of wire inside of it which has a electrical current flowing through it which in turn vibrates the speaker to make a electromagnetic wave which we interpret as sound.

"Both light and sound are waves." "and is there a physical analogous comparison of light waves to sound waves?"\n\nYes they are both waves. However, light is known as an electromagnetic wave which is a propagating disturbance of both the electric and magnetic field in space. Sound however is a pressure wave transmitted through a medium. Light waves are transverse meaning the direction of travel is perpendicular to the direction of oscillation. While sound waves are longitudinal meaning the direction of travel is parallel to the direction of oscillation. Another difference is that light waves DO NOT need a medium of travel (they can go through a vacuum) however sound waves exist only in a medium.\n\n"Sound is measured in Hz. how are light waves measured?"\nYou are correct, one measurement of sound is in Hz. However, waves have 4 unique properties. Velocity the rate that it propagates which is measured in m/s. Frequency, how many times the wave repeats itself in a period of time measured in Hz. Wavelength, the distance between complete cycles measured in meters. And finally, Amplitude or Intensity which is measured in decibels or W/m^2 which measures how high the crests become and how low the troughs become. The larger the amplitude the higher the peaks and lower the valleys. This is also measured in meters. Higher intensitys is proportional to the amount of energy the wave has. \n\nAs far as measuring a light wave, we usually measure the intensity and either the wavelength or frequency of the light wave.  The wavelength of light and sound is inversely proportional to the frequency because the velocity is fixed to the speed of sound 343 m/s or the speed of light 3.00 x 10^8 m/s.  \nThe higher the frequency of light, the more the light moves to the purple end of the spectrum (think about the rainbow). The human eye typically picks up light between 390 (purple) nm - 970 (red) nm\n\nvelocity = wavelength * frequency.

Sound travels in a wave.  Actually travels best through a solid.

Energy can not be created or destroyed, it just changes into a different form.  Usually sound waves mechanically vibrate objects, sometimes transferring the energy into kinetic energy, sometimes it is reflected or absorbed and ultimately results in heat, which is a form of mechanical vibration.

ohm, or om is correct. om is supposedly the sound vibration when the universe was created
