Age in months and ABR threshold in dB pSPL for left and right ear for all tested gerbils. Threshold was measured in 10 dB steps therefore the higher intensity indicated the level at which a response was observed. This level was also used for calculating the level 20 dB above visual detected ABR threshold (20 dB AVT). Old animals are highlighted by grey
