Difference in the intensity of sound = 25 - 15 = 10 dB So, 25 dB sound has 10 times more intensity than the 15 dB sound.
Difference in the intensity of sound 25 - 45 = 20 dB So, a sound with 45 dB is 100 times greater in intensity than a 25 dB sound.
Every 10 dB interval accounts for 10 times more intensity.
