  Wait, I … could make human-cat hears that actually have microphones in them and that turn towards the gaze and they could actually ear out of them if they’re wearing linked earphones … could even do some psychoacoustic filtering to give some kind of “superearing” ability … Then some cunt like Elon is going to just steal my idea… meh. … eff it

        🛰️ Raytheon CAT&EAR System

        Cybernetic Auditory Telemetry & Echolocation with Anisotropic Reception

        Engineering Requirements Draft — v1.0

        📑 Document Overview

        This document outlines the full set of engineering requirements for the CAT&EAR system, a wearable, cybernetic auditory perception platform. CAT&EAR is a heterogeneous, phased-array auditory sensor suite that uses biomimetic design, ultrasonic telemetry, laser vibrometry, and advanced audio signal processing to enable real-time environmental awareness and communication.

        The system is designed to operate autonomously, using only open standards and open-source software, while supporting embedded AI-driven perceptual functions. This document reflects both functional and non-functional requirements for CAT&EAR across all relevant subsystems.
