Additional Parameters:
Body weight = 14 g
Functional interaural distance= 40 µs
(Time required for sound to travel around the head from one auditory meatus to the other.)
Comments: Threshold values taken from original data. We now refer to these animals as “wild mice” as “feral” refers to domestic animals that have returned to the wild
