A sound wave is measured to have a 20-decibel sound intensity level (SIL). And the sound wave power flux (measured in Watts/m2) is then increased by a factor of 2000. What is the new sound level (in decibels) after this factor of 2000 increase in sound power?
Sound intensity level= 10log(I/I_0)
The Attempt at a Solution
10log(20 / 10-12W/m2) = 10log(20000000 MegaWatt) = 7.301
One thing i do not understand is this factor increase by 2000, therefore i am not sure what to do next.
Thanks for your help in advance
