A) have the same amplitude but different frequencies.

E) combine amplitudes and frequencies in basically the same way.

Question

Quizplus · Accepted Answer

Most natural sounds in the real world are mixtures of different frequencies and often include background noise. It is rare for natural sounds to be pure tones (one frequency and amplitude). Additionally, the frequencies in natural sounds tend to vary in range and amplitude. Therefore, option B is the best choice.
