Wireless energy transfer:

is acheived using electromagnetic resonant induction.

The resonance of live sound is acoustic resonance:

   http://en.wikipedia.org/wiki/Acoustic_resonance

Since these two forms of resonance use different mechanisms
(electromagnetic waves vs sound waves in air) they do not cross
couple, hence there is zero chance for interference between them.

The possibility of interference in electrical/computer audio
equipment (which use electromagnetics) and the wireless electricity
transfer (which also uses electomagnetic waves) deserves far more
concern.
