What is the level of loudness of a sound of intensity `10^(-12) W//m^2` ?

Text Solution

AI Generated Solution

To find the level of loudness of a sound with an intensity of \(10^{-12} \, \text{W/m}^2\), we can use the formula for loudness in decibels (dB): \[ L = 10 \log_{10} \left( \frac{I}{I_0} \right) \] where: - \(L\) is the loudness in decibels (dB), ...
