Abstract

The properties of the partially implantable middle ear hearing device (SIMEHD) were extensively studied. The internal unit was subjected to 5,000 cycles of bending at a force of 75 g (gravity) without failure. An accurate measurement of the force output of the SIMEHD was obtained (14 - 25 dynes/mA). This force is too small to cause any damage to the ossicular chain. The force resulting from electromagnetic interference over a wide frequency range (500 Khz - 1 Giga (109) Hz) was measured and noted to be within the margin of safety. The frequency response plots (500 - 8,000 Hz) were also obtained and revealed an excellent ability to amplify middle and high-frequency sounds.
