Type 4.3 Ear Simulator

Application ID: 106741

This model is of the P.57 Type 4.3 Full-band Ear Simulator. The model includes the geometry of the ear canal as well as the pinna defined in the ITU-T P.57 standard. The model also includes interpolation data for an ear drum impedance ensuring correct acoustic properties of the ear. The model tries to fulfill the geometry and acoustic requirements defined in the standard. It is not a model of a particular, commercially available, ear simulator.

The ear drum impedance data follows from the reference: L. B. Nielsen and M. Herring Jensen, “The Digital Twin of a New and Standardized Fullband Ear Simulator,” DAGA 2022.

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