Final Answer :
D
Explanation :
The decibel scale is a logarithmic scale, which means that each increase of 10 decibels represents a sound that is 10 times more intense.
Therefore, to find the number of times more intense the rock band is compared to the subway train, we need to calculate the difference in decibels between the two sounds:
130 dB - 100 dB = 30 dB
Since each increase of 10 decibels represents a sound that is 10 times more intense, an increase of 30 decibels represents a sound that is:
10 x 10 x 10 = 1,000 times more intense
Therefore, the answer is D) 1000.
