Oh, I am sorry I should have guessed you meant decibels.
Decibels are used to determine the intensity of the sound.
To be more specific, decibel is logarithmic unit; "10 times the logarithm of the ratio of the sound intensity to some reference intensity."
So, it is not related to speed of light at all to answer your question, they are merely a unit, just like meters.

http://www.phys.unsw.edu.au/jw/dB.html explains everything if you are not familiar with decibels and logarithmic functions.
A Logarithmic function is the inverse of the exponential function. A logarithmic function rises up quickly and then the increase slows down and goes to infinity very very very slowly.
For example an exponential function rises slowl ...[text shortened]... t the rear shocks after a big first shock are less dangerous and damaging.
Hope this helps.

Yes, my friend.
The speed of sound changes though. It depends of the medium.
Let me give you a simple example.
Say you put your ear to a railroad (made of iron, so solid) you can hear the sound of the train coming from 1 kms away but when you cannot hear the train from just standing there becauuse it is harder for the sound to transmit from air.

In theory, yes. I am not sure though, never been to a blackhole.
