Environmental Performance of Noise Reduction System in Cogeneration Plants—A Life Cycle Assessment Study

Although one of the most harmful factors to health is noise, it often ignored in life cycle assessment (LCA) studies. Most researches regarding noise inclusion LCA focus on problem transport and very few works consider impact emitted by other sources. This study addresses effects generated cogeneration plants. The main objective assess environmental performance reduction system considering due steam discharge as well compare loss associated with production disposal a silencer benefits resulting from its application for reduction. A method determine midpoint endpoint human indicators composition intermittent stationary source background developed. results indicate that benefit six orders magnitude greater than loss. Human attributable residential zones under consideration span wide range disability adjusted years (DALY)—0.16–136 DALY. greatest values occur densely populated areas located close source. formula proposed express annoyance residents individual depending their distance source, sound power level, existing level. Uncertainty sensitivity analyses have been carried out assuming conditions. Modifications efficiency, duration, lifetime not affected overall conclusion drawn.
