Question

how a loud sound can be produced by guitar?

Explain.​

Answer 1

Explanation:

The guitar string forces the sound box to begin vibrating at the same frequency as the string. The sound box in turn forces surrounding air molecules into vibrational motion. Because of the large surface area of the sound box, more air molecules are set into vibrational motion. This produces a more audible sound.

Answer 2

Answer:

$\huge\fbox \red{Answer}$

The loudness of a sound corresponds to the amplitude of a pressure wave; the higher the pressure at the peak of the wave, the louder the sound seems to us. The only real way to get a louder sound out of a string is to put more energy into the string, probably by plucking it harder.
