Loudness:

• Loudness is the response of ear to the sound. Loudness is proportional to the square of the amplitude of the vibration body producing sound.
• The more the amplitude of vibration, the sound is the loud. The lesser the amplitude of vibration, the sound is feeble.

Feebleness:

• Feebleness is a state of being very weak. An old man's feebleness may make it difficult for him to care for his rowdy Great Dane.
• In addition to physical feebleness, which people have when they're frail, fragile, or sickly, there's also a feebleness of will or character.

Amplitude

• Amplitude is the maximum displacement that a body attains from its mean position. Consider the following diagram of a wave.
• The displacement is varying with time. But, there are times when there is maximum displacement 'a'.
• This maximum displacement is termed the amplitude of a wave.
