Differential Intracochlear Sound Pressure Measurements in Human Temporal Bones with an Off-the-Shelf Sensor

Figure 4

Sound pressures in scala vestibuli (, (a) and (b)) and scala tympani (, (c) and (d)) normalized to the stapes footplate velocity (). For comparison the range of results obtained with a custom-made pressure sensor by Stieger et al. [6] is given (grey shaded area). Data with an SNR < 7 dB were omitted.
