Information about the End Correction Factor (k) |
In acoustics, end correction is a short distance applied or added to the actual length of a
resonance pipe, in order to calculate the precise resonant frequency of the pipe. ... A
theoretical basis for computation of the end correction is the radiation acoustic impedance
of a circular piston.
Both ends flanged: k = 0.850 One end flanged, one end free: k = 0.732 Both ends free: k = 0.614 Normally, k = 0.732 is assumed |
