ANSWER:Intensity. A whisper across an empty room is between 0 and 1 db. The intensity of sound is minimal. A jet engine would have the db level of 120 and be painful and damaging to the eardrums.

Here's a scale:

10 dB: leaves blowing in the wind

20-40 dB: a regular run-of-the-mill computer

30-60 dB: a server (like the big professional company ones. My Dell poweredge server weighs in at about 55-65 dB depending on temps and load)

75-95 dB: a car

85 dB: Here it starts damaging your hearing. Most MP3 players have a software limit at this level, ie. highest setting.

~ 100 dB: a motorcycle, Harley Davidsons and choppers are louder than this.

110 dB: a rock concert

120 dB: a jet airplane taking off (props are louder)

>200 dB: a nuclear blast from 2 km away. If you didn't burn to death, your eardrums would vaporize and even kill you because of the sheer sound pressure.

Because of the large variations in energy, between a weak sound and a loud sound, a logarithmic scale - like decibels - is appropriate.

What are waves measured in?

•Sound can be measured in many ways such as decibels. There is a special machine which you can by that measures how many decibels something makes.
