It's a logarithmic scale.
It goes up to category 5.
20,000 Hz (20kHz) is the (ideal) highest FREQUENCY that a healthy human ear can hear. With regard to loud sounds, a sound LEVEL of 120 decibel (dB) causes pain, and a level of 140 dB causes deafness.
The logarithmic unit of measurement "decibel"" is abbreviated as "dB"
decibel and richter
The Decibel was named after Alexander Graham Bell who is the inventor of the telephone and the bell is a sound known as the Decibel. The Decibel ranges from 0 to 140, with 140 being the highest.
The decibel scale is a logarithmic scale. Scroll down to related links and look at "Decibel - Wikipedia" and "Sound level meter - Wikipedia".

Really good
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.
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.
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.
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.

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.

A bar chart can provide a visual representation of the loudness in dB for activities such as concerts, traffic noise, and normal conversation. Each activity can be represented by a labeled bar with corresponding dB levels on the y-axis, giving a clear comparison of their loudness levels. This chart helps easily understand the differences in loudness between various activities.
The Welsh word for 'decibel' is desibel.
