  This paper presents a conceptual framework for perceptually optimised audio communication in high-risk and acoustically challenging environments. Drawing on principles from sound design, auditory ergonomics, and professional communication systems, the proposal integrates existing technologies into a coherent, safety-oriented solution. Designed for emergency responders, control centre operators, and other safety-critical roles, the framework focuses on maintaining clarity, protecting hearing, and supporting situational awareness under real-world constraints. This framework is intended for researchers, technologists, and policy stakeholders exploring the future of perceptual audio in safety-critical communication and is offered as a provocation rather than a prescriptive solution.
