Frequency selectivity is the auditory system’s ability to represent one frequency independently of another.

Evidence

These experiments measure a property of the auditory system called frequency selectivity, or the ability of the auditory system to represent one frequency as independent of another. From the standpoint of perception, frequency selectivity is defined as the ability to hear one frequency as being separate from another, and is very similar, but not identical, in definition to the same term when applied to physiology. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 461
