Changes in EC pressure close to the umbo [PEC(η ∼ 0+)] due to changes in condition upon dry-out. Data are from an extracted temporal bone (ID: MU13lear, same ear as Animal 2 shown in Fig. 7). The preparation was removed from the refrigerator and allowed to come to room temperature (while in a moist container) just prior to recording. The positioning of the setup (i.e., sound source, sensor, temporal bone) was unchanged throughout, the only change was time. Measurements were made approximately every 20 min and are referenced to the initial measurement (darker indicating later in time). A final measurement was made 15 h later (dashed line), presumably indicating a fully dried out condition. Stimuli were 100 dB SPL tones. MEC cavity was vented via a small hole in the bullar wall.
