What does the amplitude of a sound wave determine1 min readReading Time: < 1 minutes
The amplitude of a sound wave is the magnitude of the displacement of the particles in the medium from their equilibrium position. It is measured in terms of the maximum displacement of the particles. The amplitude of a sound wave determines the intensity of sound and the tone of voice.
The intensity of sound is the property of a sound wave that determines how much power is transmitted through a unit area in a given time. It is measured in watts per square meter. The greater the amplitude of a sound wave, the greater the intensity of sound.
The tone of voice is determined by the frequency of the sound wave. The higher the frequency, the higher the tone of voice.
