SB 1 thresholds of aged animals were significantly larger than young animals at both 65 and 75 dB SPL when f2 as an AM tone and peak-ratio was used. AM frequency of f2 was 128 Hz and sound level of L1 was either 65 (A) or 75 dB SPL (B). Dashed lines indicate medians of the SB 1 thresholds for young (red or purple dashed lines) and aged (black and blue dashed lines), respectively. Asterisks indicate statistically significant differences in SB 1 thresholds of young and aged animals using rank-sum test.
