It is important to understand that a decibel is just a unit of measure that is used to determine loudness of a sound or amount of hearing loss.
Normal hearing is found between 0 and 25 dB in adults. For children, 0 - 20dB.
Mild hearing loss is found between 26 - 40 dB in adults. For children, 21 - 40dB.
Moderate loss if found between 41 - 55 dB in both.
Moderately severe if found between 56-70 dB in both.
Severe if found between 71 - 90 dB in both
Profound if found 90 dB or greater in both

What are decible levels?
A unit used to measure the intensity of a sound or the power level of an electrical signal. Someones voice could raise by a decibel.
What is the sound of loudness measured in?
Sound levels are measured in decibels. An increase of 10dB will sound twice as loud. The average adult young man, who has not had his hearing compromised, will have a threshold of hearing of 0dB. Therefore, one-half of them will be able to hear sounds below 0dB; the other half will not. The decibel unit was first used at Bell Laboratories, with regard to transmission losses on electrical circuits. Later this unit was used for Sound. It is named after Alexander G Bell of course; hence the capital B in dB.
What are decibels a measure of?
The intensity of sound is measured in a unit called the decibel (dB), which describes the relative intensity of a sound based on an algorithmic decibel scale containing values ranging from 0 to 194. A zero value on the decibel scale represents the weakest sound audible to humans and sound intensity increases in correspondence with numeric values, the relationship among the values on the decibel scale is not linear but algorithmic. Here is an example of the decibel scale http://www.explainthatstuff.com/soundlevelmeters.html
What unit of measurement is used to compare the intensities of different sounds?
The unit is the decibel, based on a larger unit called a bel. The decibel is measured as a magnitude on a logarithmic scale, and has no dimension as such. An increase in the numerical value therefore indicates an exponential (logarithmic) increase in the actual intensity or power. Example : an increase of 3 dB is approximately twice the power, an increase of 10 dB is 10 times the power, and an increase of 20 dB is 100 times the power.
What are the 7 levels of classifications of the daisy?

How are signals converted from voltage levels to their corresponding decibel equivalents and from decibel levels to their corresponding voltage or current levels?
Scroll down to related links and look at "Conversion Voltage V to voltage level Lu and LV - Decibel (dB) level conversion to volt ".
What is the loudest decibel level for a phone amplifier?
Phone amplifiers can go up to 45 decibels, which is very loud. These amplifiers are generally used by people who are hard of hearing. Most amplifier companies sell different decibel levels so you should test out which one works for you.

How do you convert signals from voltage levels to their corresponding decibel equivalents and from decibel levels to their corresponding voltage or current levels?
convert signal gains or losses to comparative decible reading.
How the power levels are measured in communication system?
A: Dbm or decibel of modulation
Is there anything on the headphones packaging that lets you know how loud they go?
The DB levels stands for Decibel level. The higher this number is the louder the headphones go. But, you also have to remeber that to loud in headphones will cause hearing damage.
