A method of treatment includes using an electrical energizing source coupled to a current conducting coil to cause the current conducting coil to produce pulsed electromagnetic fields. A conducting membrane is placed adjacent the current conducting coil and an insulating coupling interface is placed adjacent the membrane, such that the membrane is between the current conducting coil and the insulating coupling interface. One portion of the pulsed electromagnetic fields is intercepted by the membrane so that the membrane oscillates to generate acoustic waves to tissue adjacent the insulating coupling interface and another portion of the pulsed electromagnetic fields propagates through the insulating coupling interface to the tissue.
