<br/><br/> RECD in patients with tympanic membrane perforation is lower than normal at frequencies (250 Hz - 750 Hz) we recommend that this discrepancy should be compensated for if average normal RECD are used in the pre - selection of target and gain to avoid under amplification at lower frequencies
