Noise Attenuation with Engineering Controls
Abstract
The louver was able to reduce noise levels in front of the intake. SFLC was notified of the results of this effort following the second set of power trials and they were interested to know if it is possible to reduce noise levels to below the single hearing protection range. At lower RPMs (in the 850 range) this may be feasible if the dimensions of the louver were altered (a thicker louver will result in more noise attenuation). As the engines approach 1150 RPM, the sounds generated by the engines and turbos are most likely too great to be reduced to single hearing protection by just louvers, although additional testing would be needed to confirm this. Based off quotes from the louver vendor, it is estimated that it will cost between $5,700- $7,100 per intake to reduce sound levels to single hearing protection at low RPMs. Note this price represents the price of the louver and the shipment of the louver, and not the cost of additional installation equipment.
