Stimulus uncertainty affects perception in human echolocation: Timing, level, and spectrum.

“…Echolocation involves an initial emission that ensonifies the environment, with sound echoes being reflected back to the echolocator. Echolocation is mostly associated with bats and marine animals (Griffin & Galambos, 1941; Jones, 2005), but it is by now well-documented that people are capable of using echolocation, too (for reviews see Kolarik, Cirstea, Pardhan, & Moore, 2014; Norman & Thaler, 2017; Stoffregen & Pittenger, 1995; Thaler & Goodale, 2016). In echolocating bats it has been proposed that the neural pattern of responses to echoes is consistent with an auditory system that actively predicts echo responses (Simmons, 2012; Suga & Shimozawa, 1974).…”
