Abstract: 

This report represents the final acoustic predictions for a representative MHk turbine. The goal of this work was two-fold and aimed to, 1) provide an acoustic signature for a representative MHK turbine and 2) present a framework under which MHK developers and researchers could predict turbine acoustics, prior to building and testing, to enable cost-effective quieter designs mandated by regulators. Before this year there had been no publically available data on the acoustic signature of an MHK turbine and while devices are currently being deployed, the lack in number of measurements is still a limiting factor in understanding the impact of direct noise from these devices will have on the environment. By designing a representative turbine and predicting its acoustic signature, a baseline noise level can inform both design and environmental considerations. Additionally, this work presents the steps required to perform an acoustic analysis, demonstrates where the analysis falls within the whole design framework, identifies the necessary tools, and the minimum required information.
