What is the intensity of sound of 70 decibel ? ( Given the reference intensity `I_0 = 10^(-12) " watt"//m^(2)`)

Text Solution

AI Generated Solution

To find the intensity of sound corresponding to 70 decibels, we can use the formula for sound intensity level in decibels: \[ L = 10 \log_{10} \left( \frac{I}{I_0} \right) \] where: - \( L \) is the sound level in decibels (dB), - \( I \) is the intensity of the sound in watts per meter squared (W/m²), - \( I_0 \) is the reference intensity, given as \( 10^{-12} \, \text{W/m}^2 \). ...
