用条件性回避程序测定了3头家猪的噪声定位阈值和60°间隔纯音定位能力。定位短暂噪声爆发的平均阈值为4.5°，比其他有蹄哺乳动物的阈值要准确得多，如马、牛和山羊。猪定位低频音调的能力表明它们可以使用双耳相位差提示。然而，它们无法定位4 khz及更高的音调，这表明，像其他有蹄哺乳动物一样，它们使用双耳强度提示的能力即使不是完全没有，也受到很大限制。对猪的上橄榄复合体的研究表明，在相对大小、形状和细胞密度方面，它比其他有蹄哺乳动物更像猫。
Noise localization thresholds and the ability to localize pure tones at 60° separation were determined for three domestic pigs using a conditioned avoidance procedure. The average threshold for localizing a brief noise burst was 4.5 ° which is much more accurate than the thresholds of other hoofed mammals, such as horses, cattle and goats. The ability of pigs to localize low-frequency tones indicates that they can use the binaural phase-difference cue. However, they were unable to localize tones of 4 kHz and higher, indicating that, like other hoofed mammals, their ability to use binaural intensity cues is greatly restricted if not completely absent. An examination of the superior olivary complex of pigs revealed that in relative size, shape and cell density it is more like that of cats than that of other hoofed mammals.
