Low Profile Multimodal Acoustic Treatment

DOD / NAVY
The noise signature of the USMC Expeditionary Fighting Vehicle (EFV) is excessively high for human safety factors, and impedes stealthy land operation which places military personnel at high risk of detection by adversaries. A dominant contributor of the noise is due to the air-cooled heat exchanging system that draws a large volume of air through a compact space in a short period of time. For this Phase I project, Infoscitex proposes to develop new broadband noise abatement materials that could be retrofitted to the EFV to counteract airflow generated noise. Phase I activities will involve analyzing the cooling subsystem for noise generation locations, producing novel materials with enhanced absorption capabilities, performing acoustic tests on materials, and developing a design concept that integrates these material into the cooling sub-system.
