Abstract : Noise measurements in the XM577 Command Post Vehicle were made with the vehicle both stationary and moving. Sound power level and directivity indices were obtained for the auxiliary generator. The noise produced by the moving vehicle presents a hearing hazard to personnel who have no ear protection, and direct voice communications within the vehicle were nearly impossible. The stationary vehicle with teletype and vehicle-mounted auxiliary generator operating presented no hearing hazard; but prolonged conversation will be very difficult in the XM577. (Author)
