A computationally implemented system and method that is designed to, but is not limited to: electronically determining positioning status of one or more portions of one or more humans relative to one or more locations of demodulation of one or more acoustic ultrasonic signals into one or more acoustic audio signals said one or more acoustic ultrasonic signals originating from a portable electronic device; and electronically alerting said one or more humans from said portable electronic device regarding said positioning status of one or more portions of one or more humans relative to one or more locations of demodulation of one or more acoustic ultrasonic signals into one or more acoustic audio signals when said positioning status includes a first characterization. In addition to the foregoing, other method aspects are described in the claims, drawings, and text forming a part of the present disclosure.
