... potentials in 11 royal pythons, Python regius . Vibrograms and audiograms showed greatest sensitivity at low frequencies of 80–160 Hz, with sensitivities of –54 dB re. 1 m s –2 and 78 dB re. 20 μPa, respectively. To investigate whether pythons detect sound pressure or sound-induced head vibrations, we...
