How would you prove that loudness increases with an increase in amplitude?
Understand the Problem
The question is asking for an explanation of how to demonstrate or prove the relationship between loudness and amplitude. Essentially, it wants to know how one can show, scientifically, that when the amplitude of a sound wave increases, the perceived loudness also increases. This involves understanding the physics of sound and how our ears perceive it.
Answer
By increasing the amplitude of a sound wave, you will observe an increase in loudness.
Loudness is directly related to the amplitude of a sound wave. You can prove that loudness increases with an increase in amplitude by increasing the amplitude of a sound wave and observing the increase in loudness. For example, hitting a drum harder (increasing amplitude) results in a louder sound.
Answer for screen readers
Loudness is directly related to the amplitude of a sound wave. You can prove that loudness increases with an increase in amplitude by increasing the amplitude of a sound wave and observing the increase in loudness. For example, hitting a drum harder (increasing amplitude) results in a louder sound.
More Information
The relationship between loudness and amplitude isn't linear. Loudness is proportional to the square of the amplitude. This means if you double the amplitude, the loudness increases by a factor of four.
Tips
A common mistake is to think that loudness and amplitude have a linear relationship, but loudness is proportional to the square of the amplitude.
