Question

What is the decibel level of a normal conversation which has an intensity of 3.2 × 10-6 watts/m2?

Answer 1

about 9.5 watts i think

Answer 2

L = 65 dB

Step-by-step explanation:

As we know that the intensity of the sound is given as

`I = 3.2 * 10^(-6)`

now the loudness is given as

`L = 10 Log (I)/(I_0)`

now we have

`I_0 = 10^(-12) watt/m^2`

now we will have

`L = 10 Log(3.2 * 10^(-6))/(10^(-12))`

now we will have

`L = 65 dB`
