Abstract:

Silencer selection has long been a burdensome, and occasionally iterative process. It is typically done based on tested sound attenuation values obtained using large facilities and costly equipment - making the process time-consuming and unsustainable. Fortunately, Finite Element Analysis (FEA) continues to become a more viable intermediary step between design and construction. COMSOL Multiphysics(r) is an FEA solver and simulation software. COMSOL's acoustics module can determine full octave decibel values of Transmission Loss.This paper goes through parameters and model setup in the COMSOL e

The ear is the organ responsible for the perception of hearing. Its role is to amplify, transmit and convert an acoustic wave present in the environment into an electrical pulse that can be interpreted by the brain using the auditory nerve. There are different types of hearing loss, such as conductive hearing loss, sensorineural hearing loss, or mixed hearing loss, which is a combination of the first two. Conductive deafness, the type we are interested in this work, is related to a dysfunction of the middle ear, leading to an interruption of the progression of the sound wave within the hearing
