Abstract
The accoustic noise suppression apparatus is mounted opposite a radiator which is in fluid communication with a liquid cooled internal combustion engine having fan generated air flow through the radiator to encounter the noise suppression apparatus. The noise suppression apparatus is tri-sectional, each section including accoustic energy absorbing material. The noise suppression apparatus alter the flow path of the fan driven air flow, exhausting the air to the surrounding environment while decreasing the amount of accoustic noise received by the surrounding environment.
