Harnessing Sound Power
Intro: Harnessing Sound Power
Everyone is talking about using solar panels and wind turbines to Go Green however those are far from the only sources of renewable energy; one that is almost never spoken of is sound.
Although it does take a fair amount of noise to generate a descent amount of electricity, if you think about it, say you were to harness all the noise from a football game or the hustel and bustel of a large city, by the end of the day you have a lot of power energy. And, while it is of course far from the solution to the plethora of climate problems that faces us--being as impractical and inefficient as it is--the notion of converting sound into electricity is nevertheless in my mind a very neat and fun concept to which very little attention is given.
The things you will need:
2 wires
1 volt meter
1 speaker (the bigger the better)

The things you will need:

STEP 1: Wiring the Speakers
The whole process it quite simple. The first step is to attach wires to your speaker. Your speaker may already have wires attached and if that is the case go right onto the next step.
STEP 2: Hooking Up the Speaker
The next thing to do is to connect the your positive and negative wires on the speaker to the volt meter contacts and switch it on.
Your done!
Your done!
STEP 3: More
To increase its output you can place the speaker up against a speaker playing some music or if you happened to own a jet, you could strap it onto the engine and make some serious electricity!

I am a student, I live in a shared room and I recently bought a 3D printer. I have not been able to print more than a whistle (and that was the test print) because the noise tears down the peace. Soon I will build an enclosure which will keep most of the noise inside. And to further reduce the noise I will realize your project (because noise that is been transformed to electricity is less noise that will bother me and my roommate) but not with a speaker nor a microphone, as you tried and as the comments suggest, but with a piezoelectric sensor; and that is my suggestion to you. Thanks.

mmmm, it makes me think, how about collecting electricity from silence...meaning from sound waves that we can not hear...

Use microphone instead of speaker. Microphone is a transducer which converts sound in to electrical signals. I hope it will give better results. All the best!!

Well, i did it, and it produced around 4V , from a step up transformer that i fixed with the speaker wires. But the input was my voice rather putting up the speaker and also i attached a plastic funnel to it. Help me with modification so that i can harvest surrounding sound.

This thought crossed my mind at a rock concert. Some serious sound vibrations are created at concerts, you feel it in your body. It would be awesome to figure out a way to recycle some of that energy into powering the concerts.

Well, it obviously won't power the whole concert, but the lighting elements or the lights at a concert venue could use that power.

great post - i was thinking "ear drums" :) , ear drums vibrate with sound and very sensitive, if you had lots of little "eardrums" by a road,l server farm, football stadium, train tracks etc with "ears" to funnel the sound in and linked them up in parallel...thought about it the other day then just came across this site - wishing you all the best in your projects!

sound is producing from a cinema theatre , near traffic signals, railway stations ,airdiomes, even in our hoouse sufficient amount of sound is coming through televisons, mixer, while we are talking sound is also generated , etc in our daily life by using these all pleasee give reply for my comment
why cant we use that sound to produce electricity

smaller the wire on the voice coll better power look to fine tune the mic/ speaker to the earths tone because the earth rings like a bell.if u was able to do some things with the mics or speakers to get better results. if u could stretch the wire small as a atom this would be a free source of power,everlasting.... try smaller the wire on voice coil and super size the drum and make it hard like diamonds i believe this has already been done and cover up by the big corp.. dont try and get paid for the idea just share every ware. and higher from the ground will reflect alot from air o zone and other sound waves and make it go in to the device. also telsa,s vale will work with sound too not just air and water......... this is the answer ..........

I dont understand. How by connecting the speaker wire to a multimeter set in volts, will show a voltage?
