Amplitude is the primary factor in determining the 'loudness' of a sound wave.
The perceived "loudness" of the sound varies directly as the amplitude of the wave.
Basically, a sound wave is louder if it has a greater amplitude.
Loudness is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a subjective felt impression and is in some way related to the objective measure of sound pressure.
Amplitude. (In the particle theory of light, brightness is determined by the number of photons).
Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness"
Two answers to this: Pressure as in Sound Pressure Level or, Amplitude.
The perceived "loudness" of the sound varies directly as the amplitude of the wave.
The bigger the troughs of the sound wave and height of the wave corresponds to the loudness the higher the wave the louder the sound.

Loudness is the quality of a sound that is primarily a psychological correlate of physical strength or amplitude. You can try to measure the sound pressure in decibels. Scroll down to related links and look at "Loudness in sones - Wikipedia ", Loudness level in phon - Wikipedia ", and Subjectivly sensed loudness (volume), objectively measured sound pressure (voltage).

Loudness is really a subjective measure and is often confused with objective measures in decibel units of sound pressure or sound intensity.
Intersty- is related to loudness. and Frequency- is related to pitch.
The sound color or the timbre.
Loudness.
