Question

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

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

Answer 1

The correct option is B 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.
