Mean reactance and resistance as a function of frequency in ears grouped by 226-Hz tympanogram type. Type A: normal tympanogram; Type C: tympanogram with admittance peak at a pressure <−200 daPa; Type As: peaked tympanogram peak admittance <0.2 mmho; Type B: flat tympanogram (no defined peak admittance). For clarity, the inset lines show the average standard error of the mean for the tympanogram type indicated below the respective line.
