Abstract: An example system is described that includes a head-mountable device (HMD) with a bone conduction transducer that transmits an audio signal and an inertial measurement unit (IMU) sensor connected to the bone conduction transducer. The IMU sensor detects movement of the HMD due to vibrations of the bone conduction transducer transmitting the audio signal and the IMU sensor provides outputs. The system also includes one or more processors that receive the outputs of the IMU sensor and compare the outputs of the IMU sensor with at least one reference signal. The at least one reference signal is based on the audio signal that is transmitted. The one or more processors output an HMD fitting parameter based on the comparison.
