The objective of the analysis was to engineer a barrier wall design <br />that helped reduce noise at residential receiver locations near <br />Building 14 by 5 dBA, which is noticeably quieter. The analysis <br />used hypothetical max conditions for equipment sources, which is <br />common in engineering. <br />The assumptions used for the engineering analysis were consistent <br />with MPCA guidelines. <br /> <br />Barrier Noise Analysis <br />2 <br />BOSTON SCIENTIFIC - BLDG 14 NOISE BARRIER WALL | 4 <br />ACOUSTICAL PERFORMANCE <br />Boston Scientific Building 14 <br />North <br />SUMMARY <br />BSC is committed to exceeding the State MPCA noise <br />requirements. There are multiple acoustical benefits of the <br />barrier wall: <br /> ‚Reduces BSC vehicle and loading dock noise for the <br />nearest neighbors. <br /> ‚Reduces BSC operational noise for the nearest neighbors. <br /> ‚Gives BSC flexibility to make changes to equipment <br />without exceeding the noise requirements. <br />BARRIER NOISE ANALYSIS <br />The objective of the analysis was to engineer a barrier wall <br />design that helped reduce noise at residential receiver <br />locations near Building 14 by 5 dBA, which is noticeably <br />quieter.
