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

Figure 1

Temporal bone preparation for intracochlear sound pressure measurements. (a) Cochleostomies of ~0.5 mm diameter in scala vestibuli (SV) and scala tympani (ST) (picture was taken after the experiment). The reflector was placed on the stapes footplate for LDV measurement. (b) Samba Preclin 420 LP transducers placed in SV (left) and ST (right), sealed with alginate.
