In his experiments on telephony, Alexander Graham Bell needed a scale to describe the effects of apparent poudness. He decided that a sound increase of 1 Bel is the increase that sounds twice as loud to an average person. For simplicity, this is divided into ten decibels. He named the unit.

Who invented the decibel scale?
The decibel scale was originally used to quantify signal loss in a telephone circuit. The original unit, bel, was named in honor of Alexander Graham Bell. The decibel was devised by the Bell Telephone Laboratories in the 1920's.
Who invented the decibel system?
The engineers at Bell laboratories
How is the energy of a sound wave related to its measured value on a decibal scale?
The decibel scale is a logarithmic scale. An increase of 10 points on the decibel scale means that the energy increases by a factor 10; an increase of 20 decibels means an energy increase by a factor of 10 x 10 = 100, etc.
How does mechanical energy change to sound energy on a phone?
The transducer vibrates, producing vibrations in the air in the decibel scale audible to humans.
Who invented the first scale?
Santorio was the first person to make a scale

What type of scale is the decibel scale?
The decibel scale is a logarithmic scale. Scroll down to related links and look at "Decibel - Wikipedia" and "Sound level meter - Wikipedia".
The scale used to define sound intensities?
decibel scale
What scale does the decibel go up in?
It's a logarithmic scale.
How The scale used to define sound intensities is called the scale?
Really good

What unit sound is measured in?
Decibel (dB) * The Bel is the primary unit. However, the scale is too large. So for human hearing, we use the deciBel, where each deciBel is 1/10 of a Bel. this is abbreviated dB.
What kind of damages can be to the ear with a decibel scale?
some of the damages to the ear are bad. Some are good, and some are ok.We use a decibel scale to find this information out. A decibel scale is a scale that shows you the amount of damage something can do to your ear. An example of a decibel scale would be.....loud music = 120dban infection = 90dbsports = 80dbhole in the ear drum = 100dbblows to the head = 50dbsmall bone problems = 40dbfalls or wax = 30dba jet - airplane = 140db150 is the highest or worst db you can get.And 0 db is the lowest or least worst.0-70 are minor problems.70-150 are major problems caused.
On the decibel scale an increase of decibels means an intensity increase ten times?
ten
How will an increase in amplitude and power affect dB?
The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB. If power increases by a factor of 100, that is equivalent to +20 dB.The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB. If power increases by a factor of 100, that is equivalent to +20 dB.The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB.
