Detailed Solution

The above statement is True.
Babies have soft sounds due to the small amplitude of their sounds. Sound is produced in humans due to the larynx, also called the voice box of humans. The loudness of sound depends upon the amplitude. Amplitude is the magnitude of the sound. If the amplitude is higher, the sound thus produced is loud. If we double the amplitude, the loudness of the sound increases four times.
