Low Frequency Finite Element Modeling of Passive Noise Attenuation in Ear Defenders
Noise levels in areas adjacent to high performance jets 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 de...
