The intensity of the sound is given: I=2.8*10^7 watts per square meter.
Then, to find the decibel level of this sound, replace I=2.8*10^7 into the given formula:
[tex]\begin{gathered} D=10\log (10^{12}I) \\ =10\log (10^{12}\times2.8\times10^7) \\ =10\log (2.8\times10^{19}) \\ =194.47\ldots \\ \approx194 \end{gathered}[/tex]
Therefore, to the nearest whole number, the decibel level of this animal's sound is approximately 194 decibels. Since 194 is greater than 160, then this sound can rupture the human eardrum.
