Modeling of the Vibroacoustic Behavior of Hearing Protectors Using the Finite Element Method

One of the reasons why hearing protectors are not fully efficient at protecting against noisy environments is the discomfort they induce. This discomfort may incite an individual to wear his protector incorrectly or to remove it, thereby reducing its performance. Of specific interest is the auditory discomfort that depends on the acoustic pressure value at the eardrum of the protected ear. To reduce this discomfort efficiently, a tool for the acoustical design of the hearing protector device (HPD) that allows for the prediction of the frequency spectrum of the acoustic pressure in the ear canal is useful. This is a complicated issue that requires accounting for all of the sound transmission paths (e.g., airborne and structure-borne) within the head, hearing system, and HPD system. This involves solving coupled exterior and interior problems where incoming external sound waves or internally generated sound interacts with an HPD made up of various solid, poroelastic, and acoustical domains coupled to tissues with complex behavioral laws. In this presentation, we show how the finite element approach can be helpful in predicting and understanding the vibroacoustic frequency behavior of open ears and ears occluded by HPDs such as earmuffs and earplugs, with the aim of optimizing their comfort. In particular, the use of the COMSOL Multiphysics® software to solve models of various complexities is considered and discussed. Simulation results are compared with experimental data, analytical models, and other numerical softwares.
