Question

shrill sound has a _______ pitch and dull sound has a ________ pitch

Answer 1

shrill has high and dull has low

Answer 2

Answer:

the shrill sound has a high pitch and dull sound has a low pitch

Explanation:

Hint: Pitch is basically the frequency of the sound that the human ear understands. A sound having a higher frequency is said to have a high pitch and lower frequency sounds have low pitch. A sound having higher frequencies is said to be shrill and one having a lower frequency is said to be dull.

Complete step-by-step solution:

Sound is a wave and has all the properties of a wave. Sound can also be characterized by the various properties of a wave, like amplitude, frequency, etc. Corresponding to these properties sound has defining characteristics, namely, Pitch, Loudness, and tone.

The amplitude of the soundwaves gives it loudness. A sound wave having a higher amplitude is loud and vice versa. A loud sound has a higher amplitude and more energy.

Pitch is basically the frequency of the sound that the human ear understands. A sound having a higher frequency is said to have a high pitch and lower frequency sounds have low pitch. As the frequency or pitch of the sound increases it gets sharper and shriller like a child crying or a girl screaming these are sounds having a high pitch and are considered to be shrill. Similarly, sounds of a bass drum or rumbling are sounds that have low frequency or pitch and are called dull sounds.

So, a shrill sound has a high pitch and a dull sound has a low pitch.

Thus, Option A is the correct one.
