Resum
Most cases of global active noise reduction in commuter turboprop aircraft cabins have been attempted at low frequencies. The case of noise reduction applications for a smaller piston engine aircraft has been studied less, although they are noisier than turboprops with levels of up to 100 dBA. Specifically, the case of a six-seat, two-engine aircraft is studied here for an active noise control application. The main frequencies for noise reduction have been found at BFP (75 Hz) and some harmonics...
