用行为测听法研究了强噪声暴露对虎皮鹦鹉听力的影响。在双耳暴露于强烈的宽带噪声后，使用回避条件反射技术连续测量了鸟类的听觉阈值位移（TS），频率在0.125至8 kHz之间。在高于1.5 kHz的频率下观察到临时阈值移位（TTS），在低于1 kHz的频率下观察到相当大的永久性阈值移位（PTS）。这种阈值变化的模式与在哺乳动物中观察到的相反。
The effects of intense noise exposure on hearing in the budgerigar were examined by behavioral audiometry. After binaural exposure to an intense broadband noise, auditory threshold shifts (TS) of the birds were continuously measured at frequencies between 0.125 and 8 kHz using an avoidance conditioning technique. Temporary threshold shifts (TTS) were observed at frequencies higher than 1.5 kHz and considerable permanent threshold shifts (PTS) were observed at frequencies below 1 kHz. This pattern of threshold shifts is contrary to that observed in mammals.
