We have studied ultrasonic attenuation in rotating sHe-B at low pressures (< 10 bar) in magnetic fields up to 300 mT. In a strong field, the energy gap A in sHe-B is anisotropic, and the attenuation a of zero sound depends on the orientation of A. Because vortices and the counterflow between the nor
