Fan Noise Equation. The main noise source of the motor is due to the mechanical excitation of the. There isn't a simple formula for fan noise, but the physics can be worked out from the fundamental equations of fluid mechanics and acoustics. This fan engineering handbook is a comprehensive guide on thermal design, pressure management, acoustic measurement, and fan. Proper fan selection has a major impact on airborne noise. Explain the basic definitions related to fan noise. Noise of the electric motor that drives the fan. Identify the amca standards used for testing and rating fan noise. Blade pass frequency = (number of blades) (rpm) / 60. Bpf = n t / 60 (1) where. It isn't a simple problem however. 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. Equation 1 expresses the relationship between sound pressure level and fan rotation speed, while equation 2 expresses the combined sound when there are multiple sound. The sound generated by a fan depends on the motor power, the volume capacity, the static pressure.
