ABSTRACT:
The acoustical radiation from handling empty cans and containers is reduced to sound levels which decrease the risk of hearing damage for exposed personnel by this invention. The invention comprises the temporary use of damping end-caps comprised of viscoelastic material which eliminates metal to metal contact between containers, guides, and cables and which also dissipates vibratory and airborne acoustical energy in the containers, thereby reducing the acoustical radiation.
The invention is applicable in particular to canneries and canning operations.
