Noise suppressing guard means for attenuating noise generated within the engine compartment of an earthworking vehicle. The guard means comprise a vehicle-mounted open frame member supporting a plurality of vertically disposed columnar assemblies, each assembly containing a sound-absorbing acoustic package. The means also serves to protect vulnerable elements within the engine compartment while facilitating access to engine components for servicing. The guard means permits relatively unimpeded flow of air for the vehicle cooling system.
