Abstract

To evaluate feasibility, surgical handling, audiological outcome, and coupling efficiency of a new coupler (custom-made device) for an active middle ear implant. Revision surgery after implantation of an active middle ear implant in a 66-year-old male patient with mixed hearing loss. Prosthetic hearing rehabilitation with a new coupler for round window application. The patient obtained good speech perception in quiet (word recognition scores 80%; Freiburg monosyllables) and noise (-3.3 dB SNR; Oldenburg Sentence Test). The effective gain with the Hannover coupler improved at frequencies > 0.5 kHz compared with the values reported for other round window (RW)-coupling modalities. The coupler provides a feasible option for the RW application of the middle ear implant actuator. The spring concept of the coupler needs to be improved to further standardize RW-coupling and improve coupling efficiency at low frequencies (0.5 kHz).

Auditory Perception

Auditory perception is the ability to receive and interpret information attained by the ears. Here is the latest research on factors and underlying mechanisms that influence auditory perception.
