Question

A shrill sound has a _________ frequency and a dull sound has a ___________ pitch.

• A. high, low
• B. low, high
• C. low, low
• D. high, high

Answer 1

The correct option is A high, low

Pitch depends upon the frequency of sound waves. If the frequency is high then the pitch will be high and vice-versa.
As the frequency or pitch of the sound increases, the sound gets sharper and shriller like that of a child crying or a girl screaming. Similarly, sounds of a bass drum and rumbling have low frequency or pitch and are called dull sounds.
Thus, we can say that, a shrill sound has a high pitch and a dull sound has a low pitch.
