What is the definition of an equal-loudness contour?
- A graph that shows how our hearing varies over frequency and amplitude.
Excellent! - Fletcher-Munson curves.
This is a type of equal-loudness contour, not the definition. - We perceive some frequencies as louder than others.
This is the principle, but not the actual object. - A graph that shows how our hearing varies over phase and amplitude.
The graph does not involve phase.
