Headphone on an Artificial Ear

Application ID: 74271

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.

This model example illustrates applications of this type that would nominally be built using the following products:
