A–D, Vulnerability to temporary (A, C) and permanent (B, D) acoustic injury is SEM threshold shift for wild types reduced by conjoint loss of M2 and M4 mAChRs. A, C, Mean ± versus double knock-outs, as measured 6 h after exposure to an 8 –16 kHz noise band (gray bars) at 95 dB for 15 min. B, D, Mean ± SEM threshold shift for wild types versus double knock-outs, as measured 1 week after exposure to the same noise band at 100 dB for 2 h. For both exposures, the threshold shifts are similar when measured by ABRs (A, B) or DPOAEs (C, D). Symbol key in D applies to all panels.
