PROBLEM TO BE SOLVED: To provide a measurement system capable of evaluating an acoustic device having a vibration body.SOLUTION: There is provided a measurement system for evaluating an acoustic device which has a vibration element and which lets a user hear sound by vibration. The measurement system comprises: an ear-shaped part provided with an ear model simulating a human ear and an artificial external auditory canal continuous with the ear model; and a microphone which measures air conduction components inside the artificial external auditory canal. The measurement system is configured such that vibration is transmitted from the ear model to the artificial external auditory canal, with the acoustic device brought into contact with the ear model. As the vibration vibrates inner walls of the ear model and the artificial external auditory canal so as to generate radiation component that is a new air conduction component, the air conduction components inside the artificial external auditory canal including the newly generated radiation component are measured by the microphone. |
