Explanation:

Psychophysics is a branch of psychology that is responsible for studying the relationship between the magnitude of a physical stimulus and the intensity with which this stimulus is perceived by one or more observers. Its main objective is to have the ability to find an escalation where this type of relationship can be placed.

The relationship they will have in the sensations that people will experience, such as sonority and brightness, are the intensity with which the aforementioned stimuli are perceived by these people. With all this, Dr. Azure is conducting research in the area of psychophysics.
