We propose a simple method by which we can explain the magnetic-field dependence of the longitudinal ultrasonic attenuation in a type-II superconductor. It gives a curve which is in good agreement with experimental data, in particular, near the lower critical field Hc1. We compare it with conventional methods, which is not in good agreement with the experimental data near Hc1 but near the upper critical field Hc2.
