...Michael S. Reichert; Bernhard Ronacher ABSTRACT Sound localization is fundamental to hearing. In nature, sound degradation and noise erode directional cues and can generate conflicting directional perceptions across different subcomponents of sounds. Little is known about how sound localization...

The reason is that the tympanum receives sound at both its external and internal surfaces and thus operates as a pressure difference (gradient) receiver ( Autrum, 1940 ). grasshopper hearing sound localization locust...
