Help please

ok i am having a problem on this question. If the sound intensity level for a Walkman at maximum level is 3 x 10^-2 watts per square meter and the sound intensity level of a military jet taking off is 5 x 10^2 watts per square meter, what is the difference in the decibel levels? solve without referring to the benchmark value of the intensity of sound at the threshold of human hearing.

i am having trouble solving this i first had did it 5 x 10^2/3 x 10^-2= then i got 5/3 x 10^4= 166666.67 however i don't know if this is right, can someone please help me. Thanks.

How do you define decibel level of noise?
