Redesign of the Hannover Coupler: Optimized Vibration Transfer from Floating Mass Transducer to Round Window

Figure 2

Mean SFP displacement amplitudes in response to acoustic stimulation of the tympanic membrane (~94 dB SPL) while the RW was loaded at different static forces (colored lines) and prior to HC placement (gray line). For an RW load of 15 mN the standard deviation is shown by error bars. The inset shows mean (black diamonds) differences of SFP displacements at 15 mN RW load compared to the unloaded state as well as the individual results (gray lines). Negative values correspond to decreased SFP responses compared to the noncontact reference.
