Question

Linda usually listens to music on her iPod while studying. When the volume is initially low, raising it by five decibels is highly noticeable. However, when the volume is initially high, increasing it by five decibels does not result in a noticeable change in sound. This phenomenon is best explained by_____________

Answer 1

Answer:

This phenomenon is best explained by Weber's Law.

Explanation:

According to Weber's law, the change we are able to perceive in stimuli is proportional to the initial stimuli. Therefore, if the volume was initially high, we would only perceive a change that is also "high". Five decibels aren't much when compared to a high volume. However, when the volume was initially low, five decibels were enough to be perceived.
