The Answer is The answer should include the following information: There are three properties that we can perceive when a sound is generated. 1) Loudness is determined by the amplitude or intensity of a sound wave. This property is measured in decibels. As the decibels associated with a sound increase, our perception of that sound also increases.
2) Pitch refers to the relative highness or lowness of a sound. Pitch is determined by the frequency or overall rate of vibration. Pitch is measured in hertz or the number of waves per second that are perceived. The faster rate of vibration, the closer the waves are together and the higher the perceived frequency.
3) Timbre refers to the distinctive quality of a sound. Most of the sounds we hear do not consist of a single frequency but are often rather complex with many sound-wave frequencies. Human voices have their own distinctive timbre allowing us to identify the voice of family and friends on the telephone.
