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:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
