The loudness level of ordinary conversation is `60dB`. Find the intensity of the ordinary conservation.

Text Solution

Verified by Experts

Here `L=60dB`
Using `L=10log_(10)((I)/(I_(0)))`, we get
`(I)/(I_(0))`=Antilog of `((L)/(10))`
`=` Antilog of `((60)/(10))=` Antilog of `(6)=10^(6)`
or `I=I_(0)xx10^(6)`
Since `I_(0)=10^(-12)Wm^(-2)`
`:.I=10^(-12)xx10^(6)=10^(-6)Wm^(-2)`
