How does increasing the Amplitude of a sound wave affect the sound produced?

This question was previously asked in

The correct answer is

The loudness increases

The amplitude of a sound wave is the maximum displacement of particles from their mean position, and it measures how much energy the wave carries.

Loudness is the perception of the sound's intensity, and intensity is directly related to the square of the amplitude — so a larger amplitude means more energy and a louder sound.

Pitch and frequency depend on how many vibrations occur per second, not on amplitude, so increasing amplitude does not change them.

The speed of sound depends on the medium (its density and elasticity, and temperature), not on the amplitude of the wave.

Hence, increasing the amplitude of a sound wave increases the loudness.
