The amplitude of a sound wave can be defined as the loudness or the amount of maximum displacement of vibrating particles of the medium from their mean position when the sound is produced. It is the distance between the crest or trough and the mean position of the wave. Loudness is directly proportional to the amplitude of the sound.

Amplitude is another critical aspect of sound. It describes how “tall” the wave is and is directly related to the loudness of the sound. A sound wave with a higher amplitude will be louder than a sound wave with a lower amplitude.

Amplitude refers to the distance of the maximum vertical displacement of the wave from its mean position. Larger the amplitude, the higher the energy. In sound, amplitude refers to the magnitude of compression and expansion experienced by the medium the sound wave is travelling through. This amplitude is perceived by our ears as loudness.

Amplitude, on the other hand, is related to the energy of the sound wave, often perceived as its loudness. Technically, it’s the height of the wave’s peak or the depth of its trough from the central line. Greater amplitudes produce louder sounds, and vice versa. In the world of acoustics, amplitude is usually measured in decibels (dB).
