... to sound detection under naturalistic scenarios, airborne sound stimuli presented under experimental conditions did not produce vibrations detectable to the salamander ear. Instead, threshold-level sound pressure is sufficient to generate translational movements in the salamander head, and these sound...

... was followed by a 45 ms delay before the first click and lasted until 45 ms after the last click ( Fig. 3C , Fig. 4C ), giving a length of the tone stimulus at full intensity of 225 ms. We used pure tones of 40–1000 Hz for testing vibration detection, whereas the speaker could not be calibrated adequately...
