11-03: The Cost Of Noise II

This is a follow on to the Cost of Noise paper presented in 2008 (TP08-16). The 2008 paper was focused on how noise affected project cost as a function of reduced far-field noise, for a static heat exchanger design. However, there is a second component that an air-cooled heat exchanger designer must take into account when looking at noise; specifically, how to balance the cost of the air-cooler metallurgy and design pressure with site noise requirements. In this paper, we will look at the effect of reduced far-field noise as a function of air-cooler metallurgy and design pressure. The goal here will be to demonstrate how these additional parameters influence optimum air-cooler cost design.
