Question: The human auditory system is able to detect changes in the sound intensity level as small as 1 dB. (a) What is the corresponding percentage

The human auditory system is able to detect changes in the sound intensity level as small as 1 dB. 

(a) What is the corresponding percentage change in the intensity I when the sound intensity level changes from 10 dB to 11 dB? 

(b) What is the percentage change when the intensity level changes from 80 dB to 81 dB? 

(c) What are the absolute changes in the value of I in parts (a) and (b)? Why are they different, even though the percentage changes are the same?
