Amplitude. (In the particle theory of light, brightness is determined by the number of photons).
The amplitude of the sound wave determines the loudness (intensity).
Yes the loudness of a sound is called its intensity.
Loudness of sound: Loudness is that characteristic of sound by which we can distinguish between a loud and a faint sound.It depends upon amplitude, area of vibrating body, intensity and condition of ear. Intensity of sound: Sound energy flowing per second through a unit area held perpendicularly to the direction of sound waves is called the intensity of sound.Its unit is W/m2.
intensity
By its amplitude. Really loudness is sound intensity & intensity depends on square of amplitude ie. higher the amplitude higher the intensity which means higher the loudness.

intensity
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
