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.
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.
When a sound intensity increases by factor of 10 it's decibel reading increases by blank?
Decibel Scale [Apex] (: its 10 honey
What is the purpose of mentioning db in audio system and how db works?
The dB mentioned when speaking of audio is referring to the decibel. The decibel is used to measure sound level. The purpose of mentioning it is for those who look for certain dB levels. The dB is a common measure of sound intensity that is 1 tenth of a bel on the logarithmic intensity 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. 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.
A bar chart showing the loudness in dB of different activities?
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.
What is the scale used to define sound intensities?
Take a sound pressure level meter (SPL meter). Try to measure the sound pressure p in pascals or in decibels, referred to the threshold of hearing with 20 micropascals.
