The ear integrates energy over time to lower detection thresholds for longer sounds

Evidence

The previous sections of this chapter focused on temporal resolution, or the ability of the auditory system to follow amplitude changes in a stimulus. Another well-known aspect of auditory temporal processing is that absolute thresholds of sounds depend on their duration. This process is referred to as temporal integration or temporal summation, defined as the ability of the ear to accumulate information over time to improve detection threshold. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1049
