The Everett, WA-based company magniX, recently announced noise results from flight testing of a 6-passenger eBeaver propeller aircraft, retrofitted with a magniX 750-horse power electric motor, which demonstrated a significant reduction in noise pollution from an electric aircraft versus a conventional one. When compared to the standard Beaver aircraft, the eBeaver recorded noise decreases ranging from 16-22 dBA across all phases of flight. Specifically, at take-off phase, the eBeaver recorded noise levels of 20.8 dBA lower on average and 24 dBA lower at peak compared to the standard Beaver, meaning noise energy is at least 100 times lower, the company said.
