One often needs to compute the change in decibels corresponding to a change in the physical intensity measured in units of power per unit area. Take mm to be the factor of increase of the physical intensity $($i$.$e$.,$ I$=$mI$0$I$=$mI$0).$

Part C

Calculate the change in decibels $($$2$$2,$$4$$4,$ and $$$8$$8)$ corresponding to m$=2$m$=2,$ m$=4$m$=4,$ and m$=8$m$=8.$

Give your answers, separated by commas, to the nearest integer$--$this will give an accuracy of $20\%,$ which is good enough for sound.
