  • an ear protector for providing acoustic isolation for a user in a noisy environment;

    a self-contained ranging means disposed entirely within said ear protector for detecting a moving object in the proximity, no part of said ranging means being disposed on or in said moving object, said moving object and user being present in said noisy environment, wherein said user is incapable of audibly detecting said object or its movement toward said user without using the ear a protector having an audio transducer; and

    means for generating an audible alarm signal when said moving object approaches said user, said audible alarm signal being communicated within said ear protector to allow said user to respond to said audible alarm signal without compromise of sound protection by said ear protector.
