A siren emits sound with an intensity value of \( 20 \mathrm{~W} / \mathrm{m}^{2} \), determine the decibel value. Where \( \left(I_{o}=1 \times 10^{-12} \mathrm{~W} / \mathrm{m}^{2}\right) \).

Step 1
The formula is: \[ L = 10 \log_{10} \left( \frac{I}{I_0} \right) \] where \( L \) is the sound level in decibels (dB), \( I \) is the intensity of the sound, and \( I_0 \) is the reference intensity. Show more…
