An example method for determining borehole acoustics using an electromagnetic sensing apparatus may include positioning a downhole tool within a borehole disposed in a formation. The downhole tool may comprise at least one acoustic source and at least one electromagnetic (EM) sensor. An acoustic wave may be emitted from the at least one acoustic source. The acoustic wave may generate an electrical signal when an EM field is present within the borehole. The electrical signal may be measured with the at least one EM sensor. At least one downhole characteristic may be determined based, at least in part, on the measured electrical signal.
