Figure Lengend Snippet: a Representative examples of each frequency evaluated are shown with the corresponding power spectra below. Measurements were made using a hydrophone in the same place, where the fish’s head was positioned. b Particle acceleration levels (dB re: 1 ms−2) from the underwater speaker measured in all three dimensions (x-axis = black, y-axis = light grey, z-axis = dark grey) at all frequencies exam-ined for three sound pressure levels: 139, 145, and 151 dB re: 1 µPa. Measurements were made using a triaxial accelerometer in the same place, where the fish’s head was positioned

Figure Lengend Snippet: Acoustic characteristics of the experimental tank and speaker. a Acoustic impedance [ratio of sound pressure (dB re: 1 µPa) to particle velocity (dB re: 1 ms−1)] in the z-axis (Z) relative to 1.5597 MRayl (the reference impedance for a free-field in 35 ppt salinity seawater at 15 °C) is plotted for all the frequencies examined at three sound pressure levels: 136, 145, and 151 dB re: 1 µPa. Measurements were made using a triaxial accelerometer placed in the center of the tank and water column. Multiple magnitude measurements (n = 10) for both pressure and particle velocity were made at each frequency and sound pressure level. All data are plotted as the mean ± 1 standard deviation; note that the standard deviations are very small and the standard deviation bars are obscured by the symbols. b Phase difference (Δ) between the pressure and particle velocity wave. Measurements were made using a triaxial accelerometer placed in the center of the tank and water column. Multiple phase difference measurements (n = 10) were made at each frequency and sound pressure level. All data are plotted as the mean ± 1 standard deviation; note that the standard deviations are very small (< 0.3°) and the standard deviation bars are obscured by the symbols
