Low Frequency Finite Element Modeling of Passive Noise Attenuation in Ear Defenders
… have increased monotonically in the past few years. When personnel are exposed to such high noise fields, the need for better hearing protection is inevitable. Adequate hearing protection may be achieved through the use of circumaural ear defenders, earplugs or both. This thesis focuses on …

Low Frequency Modeling and Experimental Validation of Passive Noise Attenuation in Ear Defenders
Circumaural ear cups have been used for decades as an effective way of protecting users from high noise fields. Over the decades, a number of researchers dedicated their time to understanding the dynamics that govern the attenuation of hearing protectors. This thesis duplicates some of this work …
