PPI-based audiogram in relation to behavioral audiogram. (a-i, left pane) The schematic of stimuli presented for evoking the startle responses. (a-i, right pane) Representative raw data of a force sensor output used to determine the strength of the startle response (startle value); (a-ii) The boxplots of startle strengths; (a-iii) The IR based on the startle strengths. The baseline of IR (red line) is the mean + 1σ of IRs under the startle only conditions across multiple days. The PPI threshold is defined as the smallest SPL where the IR exceeded the baseline. (b) The values of the PPI-based audiogram plotted against the values of the behavioral audiogram. (c) The values of the PPI-based audiogram after interpolating the IR function, plotted against the values of the pure-tone audiogram.
