How does our perception of sound change with intensity of the stimulus?

Question

Quizplus · Accepted Answer

Our sound perception changes at a smaller rate than the change of the intensity. This is because our perception of loudness is not linearly related to the intensity of the sound. As the intensity of the sound increases, our perception of how much louder it is increases less and less. This is why we use the decibel scale to measure sound intensity, which is logarithmic, rather than a linear scale.
