    Abstract: A computationally implemented system and method that is designed to, but is not limited to: electronically providing audio output information to one or more portions of a portable electronic device to be outputted from said portable electronic device via one or more acoustic ultrasonic signals; and electronically outputting, said one or more acoustic ultrasonic signals to be demodulated into one or more acoustic audio signals containing one or more portions of said audio output information at one or more locations spaced from said portable electronic device based at least in part according to said one or more acoustic ultrasonic signals and based at least in part according to one or more portable electronic device ultrasonic emitter arrangements. In addition to the foregoing, other method aspects are described in the claims, drawings, and text forming a part of the present disclosure.
