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
