Parakeets exposed for 72 hr to a 1/3-octave band of noise centered at 2.0 kHz have a maximum threshold shift at 2.0 kHz with little or no spread of threshold shift to lower or higher frequencies. These results differ from those observed in mammals and suggest significant differences between avian and mammalian peripheral auditory processing.
虎皮鹦鹉暴露于以2.0千赫为中心的1/3倍频程噪声带72小时后，在2.0千赫处有最大阈值偏移，阈值偏移很少或没有扩展到更低或更高频率。这些结果与在哺乳动物中观察到的结果不同，表明鸟类和哺乳动物的外周听觉处理存在显著差异。
