The answer to this question would be hearing threshold.

Hearing threshold definition is the lowest intensity of sound that still can be heard by 50% of the time. In this question, the threshold would be 15 feet. If the distance increased, the chance of calling out will be decreased.It is a bit weird though since hearing mostly use decibel as a unit, not distance.

in this scenario, Rachel's hearing threshold for detecting her friend's call is at a distance of 15 feet.The term hearing threshold denotes the sound level below which Rachel can not perceive and detect the sound. This value is different for each person and differ individually. It is used to determine a person's degree of hearing loss.
