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
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.
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.
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
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.

Hearing protection is typically required at decibel levels of 85 or higher to prevent hearing damage.
Hearing protection can effectively block out decibel levels up to around 30-35 decibels.
Sounds above 85 decibels can damage hearing, especially with prolonged exposure. The risk increases with higher decibel levels and longer exposure time. It is important to protect your ears in environments with loud noise.
The recommended decibel levels for ear protection to prevent hearing damage in noisy environments are typically around 85 decibels or higher. It is important to wear ear protection such as earplugs or earmuffs when exposed to loud noises to protect your hearing.
The highest safe decibel level for humans is around 85 decibels for prolonged exposure. Above this level, there is an increased risk of hearing damage. Sound levels above 120 decibels can cause immediate harm to hearing.
Exposing babies to dangerous decibel levels can lead to hearing damage, speech and language delays, and cognitive development issues. It can also increase the risk of behavioral problems and affect their overall well-being.
The maximum range of detection for submarines using sonar varies depending on the decibel level. Higher decibel levels can detect submarines at greater distances compared to lower decibel levels.
Any decibel level that exceeds the recommended occupational noise exposure limits is considered unacceptable. This can vary depending on the duration of exposure, but generally levels above 85 decibels can cause hearing damage over time. It's important to limit exposure to loud noises to protect your hearing.
Sounds above 85 decibels can be harmful to your ears, especially with prolonged exposure. Continued exposure to sounds above 85 decibels can result in hearing loss and damage to the delicate structures in the ear. It is important to protect your ears from prolonged exposure to high decibel levels.

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.
Sound intensity levels are measured in decibels (dB) because it allows for a more convenient way to express the wide range of sound levels that humans can hear. The decibel scale is logarithmic, meaning that each increase of 10 dB represents a tenfold increase in sound intensity. This exponential nature of the decibel scale reflects how our ears perceive sound, as our hearing is more sensitive to changes in lower sound levels compared to higher ones.
