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?
# Kingdom: Plantae # Division:Magnoliophyta # Class:Magnoliopsida # Order:Malvales # Family:Family:Malvaceae # Genus:Hibiscus # Species:brackenridgei
At what decibel level is hearing protection required?
Hearing protection is typically required at decibel levels of 85 or higher to prevent hearing damage.
What is the highest decibel level that hearing protection can effectively block out?
Hearing protection can effectively block out decibel levels up to around 30-35 decibels.
What decibel levels can damage hearing?
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.
What are the recommended decibel levels for ear protection to prevent hearing damage in noisy environments?
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.
What is the highest safe decibel level for humans?
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.
What are the potential risks associated with exposing babies to dangerous decibel levels?
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.
What is the maximum range of detection for submarines using sonar at different decibel levels?
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.
What is an non acceptable decibel level?
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.
What decibel is dangerous for your ears?
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.
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 explain the concept that sound intensity levels are measured in decibels, and how does this relate to the exponential nature of the decibel scale?
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.
