The threshold of hearing varies between individuals, but is commonly taken as 0dB. About one-half of the (undamaged, young, non noise-exposed, ... ...) people will have hearing better than the threshold, and the other half will hear worse than the threshold.
But to the point, 10dB is 10 times, 20 dB is 100 times, and 30 dB is 1000 times.
A close whisper is typically around 30-40 decibels, which is significantly louder than the threshold of hearing of about 0 decibels. This means a close whisper is roughly 1 billion times more intense than the threshold of hearing.
dB (decibels) is a unit used to measure the intensity of sound. It is a logarithmic scale that compares the intensity of a sound to a reference level, usually the threshold of hearing for the average human ear. The higher the dB value, the louder the sound.
It's 10 times louder. It is easily looked up.. Example of source: http://www.howstuffworks.com/question124.htm
No, frequency measures the pitch of a sound, not its loudness. Loudness is typically measured in decibels, which represent the intensity or volume of a sound. The higher the decibel level, the louder the sound.
The loudness of a sound is measured in decibels (dB). The higher the dB level, the louder the sound. Sound level meters are commonly used tools to measure the intensity of sound. Humans perceive louder sounds as being louder due to the amplitude of the sound waves.
Take a sound pressure level meter and measure it. 95 decibels means over the is 0 decibels is the threshold of hearing. 95 decibels means the measure over 0 decibels.

A drum kit is no decibels. The decibels depends how close you measure to the bat. The closer - the louder! And the louder you play the more decibels you get. The distance is very important if you measure with a sound pressure level meter.
130 decibels -140 decibels close up maybe louder though

Why not. Go closer to the chimes and you will measure more decibels. The closer the louder.
Yes, if you can produce more than 85dB of noise. The louder the scream above this threshold, the faster you can damage your hearing. At 100dB, it takes about 20min. Normally it is unlikely unless you scream a lot. Opera singers sometimes have hearing damage due to the loudness and time extent of their singing.

Sound is measured in decibels, dB. Ten decibels (one Bel) sounds twice as loud as another sound. One decibel is the amount of sound just distinguishably louder than another sound. Named after A G Bell of telephone fame.
A quiet conversation is about 60 decibels. The sound of rustling leaves is about 40 decibels. The sound of a mosquito at 3 meters is said to be about 1 decibel.
