20 to 50 decibels (dB).
To calculate the number of decibels that power-level-'A' is greater than power-level-'B',-- Divide 'A' by 'B'-- Take the 'log' of the quotient-- Multiply the 'log' by 10 .If the result is negative, then 'A' is that many decibels lower than 'B'.
Decibels are a logarithmic way of expressing a magnitude, megahertz is a frequency. Specifically, 1 megahertz = 10^6 cycles/second There is no answer to the question.

a jet plane at a takeoff at 100 yards is 120 dB loud
a plane has 15000 decibels, there are lots maybe upto 2000000
Depending on the plane and distance, more than 100 decibels.
20 decibels
That depends on two things: On the volume of the shouter. (There is no average shout!) And on the distance where your ears are. The closer, the more decibels are there. I suggest: Go far away from a shouter.
207 decibels.
