Abstract

Certain embodiments provide a system and method for measurement of the force applied to a bone-conduction oscillator during application to a subject, resolving the measured force relative to a pre-determined criteria, and providing an indication to the user to specify whether an external force applied to an applied force indication system coupled with a bone-conduction oscillator is within a pre-determined acceptable range. A mechanical arrangement is prescribed which allows the full extent of the force applied to be represented onto the pressure measurement apparatus. The system and apparatus may be applied onto or integrated into bone-conduction oscillators.
