The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as L = 10 lo

Inessa [10]

Answer:

50 Db

Step-by-step explanation:

we know that

The loudness in decibels is given by the formula

$L = 10log(\frac{I}{I_0})$

where

I = sound intensity in watts per square meter (Watts/m^2)

I₀ = reference intensity, = 10^(-12) Watts/m^2

For I=10^(-7) Watts/m^2

substitute in the formula above and solve for L

$L = 10log(\frac{10^{-7} }{10^{-12}})$

$L = 10log(10^{5})$

$L = 10 (5)=50\ Db$
