These two units use an inductive link to communicate with each other through the intact skin in order to drive an implanted transducer.Study sample:In this study, the design of the full BCI system has been described and verified on a skull simulator and on real patients.Results:It was found that the maximum output force (peak 107 dB re 1 μN) of the BCI is robust for skin thickness range of 2–8 mm and that the total harmonic distortion is below 8% in the speech frequency range for 70 dB input sound pressure level. The current consumption is 7.5 mA, which corresponds to 5–7 days use with a single battery.Conclusions:This study shows that the BCI is a robust design that gives a sufficiently high output and an excellent sound quality for the hearing rehabilitation of indicated patients. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
