Abstract: A method, an apparatus and a system for testing a bone conduction communication device is disclosed. A vibration exciter is disposed at a wearing position of an artificial head model where the bone conduction communication device is located. The method comprises: transmitting a test audio to first and a second digital signal processors; transmitting an audio signal processed by the first digital signal processor to the vibration exciter, and simulating vibration of a bone at a corresponding part by which human generates sound using the vibration exciter, to generate a vibration signal; transmitting an audio signal processed by the second digital signal processor to an artificial mouth and simulating human sound production to generate an acoustic signal; collecting the vibration signal and the sound signal using the bone conduction communication device, and testing the bone conduction communication device according to the collected vibration signal and sound signal.
