Fan Noise Frequency at Autumn Kibler blog

Fan Noise Frequency. The majority of the sound emitted by a fan is random with respect to frequency and time. Noise data are presented here using a variety of. Identify the amca standards used for testing and rating fan noise. A typical fan noise frequency spectrum is made up of tones at multiples of the blade passage frequency bpf (bpf = b.n where b is the number of blades. The principal causes of fan noise are airstream turbulence and mechanical components connected to the fan. Note that the energy in the sound may be very. The trailing eddies produce a broad spectrum of random noise, modulated by the fan blade frequency. This article discusses fan acoustics, such as fan sound, its measurement and common fan noise reduction methods. Explain the basic definitions related to fan noise. Bpf = (2400 rpm) (10) / (60 s/min) = 400 hz. Thus the sound from a fan can be regarded as noise. The outward pulses, of course, occur at the blade.
