Discussion
20 comments analyzed.
Competitors mentioned: CDC NIOSH noise measurement app, Calibrated sound meter hardware
Concerns raised: Legal information appears AI-hallucinated and inaccurate across jurisdictions, Sound measurement accuracy unreliable without calibrated hardware, Microphone frequency response varies significantly across devices, Decibel thresholds don't match actual local laws (Philly, Fort Worth examples), Two-party/one-party consent claims incorrect and vary by jurisdiction
Feature requests: Calibration using device-generated reference tones played through phone speaker, Relative sound level readings instead of absolute decibel claims, Actual legal research instead of hardcoded/AI-generated thresholds
