Headphones are closely coupled to the ear, and so it is not possible to measure their sensitivity in a classical acoustic free-field setup used for loudspeakers. The measurement requires the use of artificial heads and ears to accurately represent the usage conditions. This model shows the coupling of a circumaural headphone to a generic artificial ear. The model uses the Poroelastic Waves physics interface to model the foam. The built-in Interior Perforated Plate model is used to represent perforates and meshes in the headphone casing. The artificial ear is coupled to a simplified ear canal and the impedance of the ear drum is specifically considered. An equivalent electrical circuit is used to model the driver in the headphone.
