If 10 decibels is 10 times more intense than one decibel, how many times more intense is 20 decibels than one decibel?

To understand the relationship between decibels and sound intensity, it's essential to recognize that the decibel scale is logarithmic. When measuring sound intensity, each increase of 10 decibels corresponds to a ten-fold increase in intensity.

In this case, when moving from one decibel to ten decibels, the intensity increases tenfold. Therefore, ten decibels is indeed 10 times more intense than one decibel.

When we look at the increase from one decibel to twenty decibels, we need to consider that this transition encompasses two intervals of ten decibels:

1. From one decibel to ten decibels (10 times more intense).

2. From ten decibels to twenty decibels (again, 10 times more intense).

To find the overall increase in intensity from one decibel to twenty decibels, we multiply the intensity increase for each interval. Thus, the calculation follows as:

10 (for the first increase from 1 to 10 decibels) multiplied by 10 (for the second increase from 10 to 20 decibels) equals 100.

Therefore, twenty decibels is 100 times more intense than one decibel, confirming that the correct
