there are two basic ways:
you can prevent sound being generated or make it less noisy
you can decrease our perception of sound - prevent it to get to our ears (ranging from sound insulation of a producer of sound like a motor to the use of sound insulating windows to earplugs...)
A practical example:
Refraining from yelling your head off in your class room will reduce sound levels in your class.
Making your teacher a present of a pair of earplugs (be careful to wrap them real nice) could reduce the perceived loudness of the sound you are making while yelling. Though the problem will be to get him/her actually wearing it.
You should not have any problems looking up the subject on the internet. If you can use Yahoo Answers you also are able to use google. There is one link for you, up to you to find the rest.

Well if you are talking about ambient nose, not sound levels on a sound system, there are several things.
1. The use of fabric and soft surfaces muffle sound, so carpeting and drapes will deaden sound
2. The more humans in a place the harder it is to hear (the bodies act as their own sound barrier
3. Acoustic Tiles on ceilings and walls
4. Rules regarding sound , an example is the being quiet in a library or during a show.
5. Trees , grass and Sound Fences can reduce sound from the outside from getting in, especially if you are located near a major road.
6. Distance , the further you are from a sound source the more reduced the sound.
7. White noise or backgroud music (They play this stuff in elevators to disguise the noise of the equipment)
8. Headphones that muffle, not take out noise
9. Turn the volume down on speakers, phones and PA systems

as u kknow sound is formed from vibrations, the only way to reduce the sound is by absorbing these vibrations, one good thing that absorbs vibrations is carpets, or styrafoam, cotton(mainly soft stuff)......on the other hand brick, wood..etc reflect the vibrations and then an echo is formmed. i think u might wanna know: that vibrations travel the fastest in solids the liqueds and slowest in air....good luck on ur project...

Well, without knowing what the project is, nor where, it is difficult to suggest an option.
Sound travels in waves, and anything that can scatter, absorb, or divert those sound waves, will reduce the audible decibels level.
Please provide more information as to your project, so we can provide more accurate sound absorption options.

keep all door/windows firmly shut. Block any holes underneath Pull blinds down, and personally reduce the noise level by reducing the volume a bit.

Wear ear protection such as ear plugs, lower the volume of loud music or just avoid areas with high noise volume.

Turn the sound down

in a house, get rid of all the smooth surfaces as possible--those reflect the sound waves.

Are we being a little bit naughty here and not looking for the answers ourselves?
