Answer :
A high-frequency sound source produces a high pitch and low amplitude.
Sound is produced by our vocal cords, precisely by the vibration of our vocal cords. When they vibrate they have a particular setup of voice mix like it has low or high frequency and low or high amplitude. The voice in the same frequency is called tone. In this type of voice, there is no voice modulation. A sound which is produced with a high frequency has shrill effect and has high pitch. Since, pitch and amplitude are inversely proportional to each other. If we have a high pitch, then we have a low amplitude automatically. Speed is determined by medium through which it passes. Hence, it is clear that a high-frequency sound source produces a high pitch and low amplitude.
