Question:I have been researching green energy and I have begun to wonder about this question. Sound is a transfer of energy. Could sound somehow be used to create energy? Its not like we are going to run out of sound.
Answers:Our ears are very sensitive... what we hear as a 'loud' sound doesn't have much energy associated with it.
A 500W speaker can be very, very loud. And it won't be 100% efficient at producing sound, it might only be making 400W of sound for example.
When you try and harness sound (using a piezoelectric, say), you wouldn't be 100% efficient, you might only harness 300W of those 400W.
So you might be able to harness 300W from a really loud sound. Vestas V-90 wind turbines have a maximum power output of 3,000,000W and a nuclear power station has about 1,500,000,000W.
Also, I'm not aware of any natural sources of sound energy that would be intense enough.
I'm almost certain that sound is a no-go!
Question:Hello I'm currently working on physics project about physics of sound.
There are some questions however.
Are there any occasion or examples that sound energy turns into other form of energy such as heat? or electronic?
Thank you !
Answers:After any sound dies down to the point where it's "gone"--that energy has gone to heat. A common conversion from sound to electricity occurs in a microphone, usually using some movable diaphragm attached to a magnet with pick up coils which have an induced EMF caused by the varying magnetic field of the moving magnet.
Question:can you help me I need to know about facts for light and sound energy
Answers:I know they will have a lot more information than you need, but wiki has articles on light and sound. If you Google these, you might find a site which covers what you want in a fairly brief and painless way. On topics like this, I have found that that is usually the case. It's always good to look at different sites to see if there is agreement because there are some sites which mean well, but don't have all the facts straight.
Question:Which is an example of sound energy?
waves moving through air after a crash
waves from a star seen in the sky
a television signal lost because of a storm
Answers:The first one is the likely answer --- waves moving through air after a crash.
The second one can't be true, because sound can not travel through a vacuuum.
Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations.
The mechanical vibrations that can be interpreted as sound are able to travel through all forms of matter: gases, liquids, solids, and plasmas. The matter that supports the sound is called the medium. Sound cannot travel through a vacuum.
Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction.
What Is The Advantages Of Magnet Energy :www.Magnets4Energy.usClean Energy Source, Magnetic Electric Generator. Everyone in this world is suffering from pollution these days. The major contribution in spreading this pollution has been added by power generating companies who release their pollutants in air and chemicals in the water. They mostly use liquid especially fossils fuels for power generation. These fossils fuels contain harmful gases and other chemicals which are major threats for the cleanliness of our environment. Also, continuously rising energy prices have compelled people to move towards cost efficient as well as environment friendly alternatives of producing power. Solar panels and wind turbines are the best ways to produce environment friendly and free of cost electricity. One problem which makes them less popular is the initial investment which required for their installation and the maintenance of these devices. So, magnetic generator is the only way left to produce cheap electricity, which is environment friendly also.The procedure through which it generates power is very efficient and less harmful for our surroundings. Unlike solar panels and wind turbines, it does not require a large space. A magnetic electricity generator has no disadvantages or threats to environment because once it starts, it works on the thrust of powers. It contains magnets that move constantly due to their unique property of polarity. It has very special characteristic that it does not produce any type of sound and ...
Sound :Check us out at www.tutorvista.com Sound is a travelling wave which is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations. Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction, while transverse waves (in solids) are waves of alternating shear stress at right angle to the direction of propagation. Matter in the medium is periodically displaced by a sound wave, and thus oscillates. The energy carried by the sound wave converts back and forth between the potential energy of the extra compression (in case of longitudinal waves) or lateral displacement strain (in case of transverse waves) of the matter and the kinetic energy of the oscillations of the medium
