Aurelian Pennycuick-Osei

Support 3 senior consultants on 22 active projects, including 6 K-12 schools, 4 clinics, and a 900-seat concert hall renovation. Ran ASTM E336 and E1007 field sound-isolation tests on 140+ wall and floor-ceiling assemblies; 94% met design targets on first test. Built ODEON and EASE room models for 9 classrooms and 2 rehearsal halls; recommended absorption changes that cut reverberation time from 1.4 s to 0.6 s. Modeled mechanical and rooftop equipment noise in CadnaA for 5 sites and drafted mitigation that kept property-line levels under Maine DEP limits. Drafted 30+ technical memos and 8 full design-phase reports, and marked up architectural drawings with partition and ceiling details in Revit and Bluebeam. Logged long-term environmental noise surveys with Larson Davis LxT meters, including 2-week monitoring at a proposed wind farm substation.

Measured transmission loss of 18 lightweight panel samples in the reverberation chamber and processed data in MATLAB. Co-authored a conference paper on low-frequency absorption of recycled-fiber panels presented at an Acoustical Society of America meeting. Calibrated microphones, sound level meters, and impedance tubes, and kept the lab equipment log audit-ready.

Ran HVAC noise measurements in 12 occupied office floors and compared results against NC and RC criteria. Helped set up vibration monitoring near a light-rail construction zone and summarized peak particle velocity data for weekly client updates.
