Fig. 10. (A) Sample distribution of sound pressure level (SPL) across stimulus rate
for sounds evoked bilaterally and unilaterally from the same fish (90 ms
sweeps at 100150 Hz). (B) SPL difference between bilaterally and
unilaterally evoked calls (mean ± S.D.; N=4). SPL
was measured as the average pressure (re: 20 µPa) over the duration of a 90
ms stimulus sweep.
