Also place the fan shroud closer to the center (the round part on the ceiling). It was difficult to insert a $$ because you are trying to fit a square box into a square box of almost the same size. called "FrequencySee"), tuned to 20-20,000 Hz), 3 main sounds could be heard: - The main noise continent is at a frequency of 120 Hz at 58 dB (ac hum, harmonic 60 Hz) - The next loudest sound is noise wind, approx 55 dB - Then a hiss-like tone appears i.e. at 1200 Hz at 50 dB (higher number = louder tone) (that was about 3 meters from the fan) (my fan blade was painted black)
