The loudness of a sound is related to its intensity, which in turn is proportional to the square of the amplitude of the sound wave. A sound wave with a larger amplitude carries more energy and is perceived as louder.

Loudness is the perceptual attribute of sound that is most closely related to the intensity of the sound wave, which depends on its amplitude.

Frequency is related to pitch (how high or low a sound is). The speed of sound depends on the medium through which it travels, not its loudness. Pitch is determined by frequency. While frequency and waveform also contribute to the overall perception of sound, amplitude is the primary determinant of loudness. Loudness is typically measured in decibels (dB).
