Room Fingerprint — Acoustic Location Tracking: 40–200Hz Chirp Sweep + Hacked Phone Mic + Room Mode Response = Victim Location in 200ms

Room acoustic fingerprinting as surveillance: each room's first axial mode (bathroom 78 Hz, kitchen 45 Hz, bedroom 41 Hz, office 57 Hz, corridor 95 Hz, car 122 Hz) creates a unique frequency response. Attacker sweeps 40–200 Hz through any audio source accessible to a hacked phone microphone, reads the resonance pattern, and identifies the victim's current room within 200 ms. Real-time spectrogram display per room. Q factor and T60 per room. Victim movement detected in real time.
