Weld

Answer 1

Answer:

Whereas loudness depends on the energy of the wave. In general, the pitch is the reason behind the difference in voice quality of different individuals. The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves

amplitude

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.

Answer 2

Explanation:

The loudness of sound depends on the amplitude of vibration of the source producing the sound waves.Greater the amplitude of sound waves,louder the sound will be.

Amplitude is linked with loudness.

The loudness of sound is measured in dB 'decibel'.

The softest sound which human ears responded is loudness of 0dB.
