Multiple Choice

Refer to the figure.
Based on the information in the graph, what would you predict is the sound frequency (kHz) of male cricket calls?

• A) 3-kHz, because the intensity threshold is at its highest point and it is a low-frequency.
• B) 5-kHz, because the intensity threshold is at its lowest point and it is a low-frequency.
• C) 40-kHz, because there is a dip in the intensity threshold and it is a high-frequency.
• D) 100-kHz, because the intensity threshold is high, and it is the highest frequency recorded.
