Abstract
Conventional bone-conduction and bone-anchored hearing aids are tested with skull simulator devices; individual adjustments are reliant on p sychoacoustic free-field audiometry, which can be quite demanding for the patient. A method is presented in which the induced skull vibratio ns are measured with an accelerometer and then analysed with Fast Four ier Transformation (FFT). With this method, frequency characteristics, harmonic distortion and dynamic response can be analysed.
