使用条件心率和肌肉活动反应来测量铁鼻ophus的行为听力图。听力图与诱发电位“开启”反应阈值曲线非常相似。它们显示出低于15 kHz的每倍频差为30 dB的低频滚降，三个低阈值区域的SPLs约为0 dB，由两个SPLs为25-30 dB的不敏感峰隔开。在80 kHz以上（45-85之间的q值）的急剧调谐阈值最小值之后是160-170 dB/倍频的高频滚降。
A conditioned heart rate and muscular activity response was used to measure behavioural audiograms inRhinolophus ferrumequinum. The audiograms are very similar to the evoked potential “on” response threshold curves. They show a low frequency roll off of 30 dB per octave below 15 kHz and three areas of low threshold with SPLs of about 0 dB separated by two insensitivity peaks with SPLs of 25–30 dB. The sharply tuned threshold minima above 80 kHz (Q-values between 45–85) are followed by a high frequency roll off of 160–170 dB/octave.
