# Name the factor on which loudness and softness of sound depends on.

The loudness and softness of sound depend on the amplitude of the wave. More the amplitude more is the loudness.

• The loudness of sound is directly proportional to the square of the amplitude of vibration producing the sound.
• Amplitude determines the loudness of a wave. The greater the amplitude, the greater is the loudness.
• Loudness is defined as the property of sound used to differentiate between loud and faint sound.
• Sounds above 80 dB becomes noise to human ears.
