What Is Blade Passing Frequency . The fan blade pass frequency noise level intensity varies with the number of blades and the rotation speed of the wheel and can be expressed as bpf = n t / 60 (1) where bpf =. This is similar to the sound heard when a moving object passes a stationary object (such as an automobile passing a person standing still). The blade pass frequency is the rotor speed (r) multiplied by the number of blades (n). Passing the stator blade is described by the discrete frequency components of sound pressure at zero frequency k = 0, blade passing ( k = 1 ). F d = n · z 2 ·. During fan operation, the following resonant frequencies can force a blade to vibrate at its natural frequencies : These are called blade passing frequencies:
