Furthermore, previous work has shown that the effect of magnetic fibrils on p-mode oscillation frequencies is enhanced by 1/f, the reciprocal of the fibril filling factor, over the effect of an equal amount of flux in diffuse form. Previous calculations have used multiple scattering methods which effectively preclude the inclusion of stratification or consideration of realistic geometries. In this paper an alternative simpler method of treating fibrils is developed on the basis of mean-field theory originally developed by Parker (1982).
