Acoustic Analysis of Leaks Around an Earbud

Application ID: 85191

This conceptual model analyzes the influence of leaks on the acoustic response of an earbud speaker placed in an ear-canal-like geometry. Built-in impedance models are used to capture the effects of a perforated plate in front of the speaker, skin impedance, and eardrum impedance.

The model contains a small gap representing a leak to the exterior. The effect of changes in this leak is introduced to analyze how sensitive the design is to the leak extent.

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