OBJECTIVE Cochlear microphonic responses (CMs) were measured in a rabbit model in the intact ear (CM1) and in ears with a partially implantable piezoelectric middle ear implant (P-MEI) (CM2) to investigate the characteristics of speech transmission of the P-MEI in vivo. DESIGN The spectra of pure tones, voices, and elicited CM1 and CM2 obtained from the(More)
OBJECTIVE To investigate the characteristics of tone burst transmission of the middle ear implant(MEI). METHODS Ten adult rabbits with normal hearing were used. A silver ball electrode was placed at the round window membrane to measure cochlear microphonics (CM) when sounds were presented before and after the implantation of the MEI. The tone burst was(More)
