ABR thresholds for 8 kHz stimuli as a function of age. Data for both male and female B6 and B6.CAST mice are shown. Linear regression equations reflect ABR 8 kHz threshold aging rates and are based on combined male and female data. There were no significant gender differences. Regression line equations: B6: y = 4.22x +23.4 (dB SPL) and B6.CAST: y = 2.79x +26.8 (dB SPL). The rate of increase in threshold with age for the B6 strain was significantly higher than the B6.CAST strain. NR = no response.
