One important characteristic of equal loudness curves is that they get flatter indicating that
A) As amplitude increases different frequency tones (500, 1000, 2000 Hz) contribute less perceived loudness
B) As amplitude increases different frequency tones (500, 1000, 2000 Hz) contribute more unequally to perceived loudness
C) As amplitude increases different frequency tones (500, 1000, 2000 Hz) are perceived to be more alike in perceived loudness
D) As amplitude increases different frequency tones (500, 1000, 2000 Hz) are perceived to differ more in perceived loudness

Quizplus · Accepted Answer

As amplitude increases, different frequency tones (500, 1000, 2000 Hz) are perceived to be more alike in perceived loudness, resulting in a flatter curve. This means that the same increase in amplitude across different frequencies will result in a similar increase in perceived loudness. Therefore, this characteristic of equal loudness curves is important for understanding how different frequencies contribute to overall perceived loudness.
