Question

The relation between the objective measurement of intensity of sound, $I$ and the subjective sensory response called loudness $L$ is given by :

• A. $I=KlogL$
• B. $L=KlogI$
• C. $L=I$
• D. None of these

Answer 1

The correct option is B $L=KlogI$

loudness($L$) in terms of intensity ($I$) is

$L=K\log \left(I\right)$

Where $L$ is the loudness, $I$ is the intensity and $K$ is a constant of proportionality.

so the answer is B.
