As hearing loss is becoming an increasing issue, new implantable hearing devices are developed. One of these implantable devices is the The Floating Mass Transducer (FMT). The FMT is a cylindrical hearing device that is implanted on one of the middle ear bones between the cochlea and the tympanic membrane. It works by vibrating at the same natural frequency as the middle ear bones, enlarging its amplitude in vibration, and thus increasing the signal to the cochlea. In this paper a study is performed to find out which parameters influence the behaviour of the FMT, and what needs to be taken into account to create a reproducible device. Five models at a 5:1 scale are designed, and a fully coupled simulation is made for the FMT. This simulation includes a coil and magnet interaction simulation, a spring constant calculation and a lumped mechanical system calculation. Using of the shelf materials, and 3D printing techniques, prototypes of the models are produced. The simulation made is validated using test results of the prototypes, and new models are designed using the simulation. The simulation and prototypes are compared using a velocity-frequency graph. A final model is presented which both in simulation and prototyping obtains as a result a velocity peak at a frequency that matches the middle ear.
