The approximate loudness of a rock concert with a sound intensity of 10⁻⁹ is 110 Db.
Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.
The loudness (L) measured in decibels (Db), of sound intensity (I), measured in watts per square meter, is defined as
[tex]\rm L = 10 \ log \ \dfrac{I}{I_o}[/tex]
where [tex]\rm I_o = 10^{-12}[/tex] and is the least intense sound a human ear can hear.
The approximate loudness of a rock concert with a sound intensity of 10⁻¹ will be
[tex]\rm L = 10 \ log \ \dfrac{10^-^1}{10^{-12}}\\\\\rm L = 10 \ log 10^1^1\\\\L = 10*11\\\\L = 110[/tex]
The approximate loudness of a rock concert with a sound intensity of 10⁻¹ is 110 Db.
