Amplitude. (In the particle theory of light, brightness is determined by the number of photons).
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.
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.
The loudness of sound is determined by the amplitude or intensity of the sound wave. Greater amplitude or intensity results in a louder sound. The unit used to measure loudness is decibels (dB).
Loudness is to brightness as sound is to light.

The loudness of sound is typically measured in decibels (dB) and is influenced by the intensity of the sound wave. As the intensity of a sound increases, the loudness also increases, resulting in a perception of the sound being louder. The relationship between intensity and perceived loudness is not linear, as the human auditory system follows a logarithmic response to changes in sound intensity.

The relationship between sound intensity level and the perception of loudness is that as the sound intensity level increases, the perception of loudness also increases. This means that the louder the sound, the more intense it is perceived to be by our ears.
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.
Sound intensity is a physical quantity that measures the amount of sound energy passing through a unit area, expressed in watts per square meter. Loudness, on the other hand, is a perceptual response to sound intensity and is subjective. In general, as sound intensity increases, the perceived loudness also increases. However, the relationship between intensity and loudness is not linear but follows a logarithmic scale.
