The correct statement is: **Intensity is a universal measurement, and loudness varies from person to person.**

To elaborate:

- **Sound Intensity** is an objective measurement that quantifies the power carried by sound waves per unit area, typically expressed in watts per square meter (W/m²). Intensity can be measured and compared across different environments without considering human perception.

- **Loudness**, on the other hand, is a subjective perception of sound that varies from person to person. It relates to how we perceive the intensity of sound and can be influenced by factors such as frequency, duration, and individual hearing sensitivity. Loudness is often measured in phons or sones, rather than decibels, which are more closely associated with intensity.

In summary, while intensity provides an objective measure of sound energy, loudness is about human perception, making it highly individualistic.
