ABR and behaviorally determined hearing loss.

<p><b>A</b> Significant one-factorial ANOVA (mean ± SEM) of the hearing loss (in percent relative to pre trauma) over the different stimulation frequencies as obtained by ABR measurements of all investigated animals. The yellow area indicates the trauma frequency. <b>B</b> One-factorial ANOVA of the hearing loss obtained by behavioral threshold paradigm (stimulus set 1). The statistics indicate only a tendency for frequency specific hearing loss around the trauma frequency. In both methods of HL determination the trauma frequency is affected most.
