What are three characterstics of sound

Sound can be characterized by the loudness, pitch and quality.

Loudness:

• Based on the amplitude of a sound wave, we can determine the loudness of the sound. When the amplitude is high, it will produce a sound that is loud and when the amplitude is low, it will produce a sound that is soft.
• Loudness is proportional to the square of the amplitude. This means that if the amplitude is doubled, the loudness increases four times.

Pitch:

• Pitch denotes the shrillness or flatness of a sound. Sound can be high or low.
• A woman’s voice generally has a high pitch than a man’s voice. This is because the frequency of a woman’s voice is higher.

Quality (Timbre):

The quality of a sound is that property by virtue of which two sounds of the same pitch and loudness produced by the two different musical instrument or people can be distinguished.
