How To Reduce Blade Pass Frequency . This may be defined as an effect characterized by a. A redesign of an existing fan. The blade pass frequency is calculated by multiplying the number of fan blades by the rotating speed of the fan wheel (rpm) as shown. A key failure cause in multistage turbines are blade passing frequencies being excited resulting in blade failures in the rotor. The blade pass frequency noise generated by a fan can be very intense and varies with the number of blades and the rotation velocity. The noise reduction values could potentially reach 6 db specifically at the critical blade pass frequency, which significantly. In order to mitigate this tonal disadvantage, we investigate mechanisms that reduce the noise levels of the blade passing. During fan operation, the following resonant frequencies can force a blade to vibrate at its natural frequencies :
