No exposure (no treatment)	5	6, 7, 7, 7, 8	7
Opera (pre-treatment)	4	7, 8, 8, 11	8
Mozart	5	19, 20, 20, 83, 84	20

Frequency
100 Hz	4	7, 7, 8, 12	7.5
500 Hz	4	7, 8, 8, 10	8
1000 Hz	4	7, 8, 10, 10	9

^a All exposures were at 60 dB; there were no significant differences between the no-exposure group and any of the single-frequency groups on log rank test.

STs, allograft survival times; MST, median allograft survival time.
