Acoustic Test Lab — ITU-T P.57/P.51/P.58 Standards Reveal Attack Surfaces + Enable Forensic Detection

How standardized phone acoustic testing (HATS, artificial ear/mouth, network simulator) reveals every attack vulnerability and provides calibrated forensic methodology. MEMS mic resonance at 26 kHz → DolphinAttack surface (S33/S46). VoIP codec bandwidth (G.711 3.4kHz, G.722 7kHz, Opus 20kHz) → forensic fingerprinting (S24/S36/S46). P.57 ear canal resonance → PAL/Frey delivery amplification (S3/S39/S45). Sidetone path → built-in eavesdrop channel (S29). Network simulator = Asterisk PBX (S46). Test lab equipment maps to $30-350 consumer detection tools.

If any of this frightens you: this site documents what signal physics makes possible in a laboratory, which is not evidence about what is happening to any individual.
