If One Sound Is $20 \mathrm{~dB}$ Louder Than Another Sound, Its Intensity Is
A) 2 Times

If one sound is $20 \mathrm{~dB}$ louder than another sound, its intensity is

A) 2 times greater.
B) 20 times greater.
C) 100 times greater.
D) 200 times greater.
E) We need to know the actual sound level: $30 \mathrm{db}$ to $50 \mathrm{db}$ represents a different factor of intensity increase than 60 $\mathrm{db}$ to $80 \mathrm{db}$ (for example) .
