How does loudness of sound vary with amplitude

1.	How does loudness of sound vary with amplitude
Answer» The amplitude of a sound WAVE determines its loudness or VOLUME. A larger amplitude means a louder sound, and a SMALLER amplitude means a softer sound. The frequency of a sound wave is what your ear understands as pitch. A higher frequency sound has a higher pitch, and a lower frequency sound has a lower pitch The human ear can detect a wide RANGE of frequencies. Frequencies from 20 to 20 000 HZ are audible to the human ear
