The purpose of this study was to determine if the Japanese quail, a domesticated, gallinaceous bird, could detect infrasound. Behavioral thresholds were determined for three birds, two males and one female, ranging from 16 Hz to 8 kHz. The animals' hearing range, at a cutoff of 60 dB SPL (re 20 μN/m), covers 6.88 octaves, ranging from 59.5 Hz to 7 kHz. All animals had the greatest sensitivity to 2 kHz, with an average threshold of 4.4 dB SPL. Although the birds' threshold at 16 Hz was equivalent to that of humans, at no frequency did the birds' sensitivity ever exceed that of humans. Therefore, the Japanese quail does not hear infrasound.
这项研究的目的是确定家鸡——鹌鹑，是否能察觉到次声。三只鹌鹑（两公一母）的行为阈限从 16Hz 到 8kHz 进行了测定。在 60dB SPL（20 μN/m 参考值）的截止值下，动物的听觉范围覆盖了 6.88 个八度音阶，从 59.5Hz 到 7kHz。所有动物对 2kHz 的敏感度最高，平均阈值为 4.4dB SPL。尽管鸟类在 16Hz 的阈值与人类相当，但在任何频率下，鸟类的敏感度都从未超过人类。因此，鹌鹑听不到次声。
