MimiMamori: Noise Dosimeter

Track cumulative workplace noise—not just a momentary dB reading. Follow OSHA and NIOSH dose, 8-hour TWA, calibration status, and an honest uncertainty range in one view.

MimiMamori is a workplace noise dosimeter that accumulates exposure over a shift. It calculates OSHA PEL, OSHA Action Level, and NIOSH REL side by side, with Dose%, projected end-of-shift dose, 8-hour TWA, and an estimate of time remaining to 100%.・Calibration with visible limits Calibrate against a 94/114 dB acoustic calibrator, a professional meter, or a posted zone level. The app keeps calibration status and estimated uncertainty visible instead of presenting a phone microphone as certified equipment.・Shift records and reports Store sessions, notes, and statistics on device, then create a PDF report from selected records. Audio is reduced to sound-level measurements in memory and is not saved as a recording.

Important: This app is a reference aid for workplace awareness. It does not replace a certified sound level meter, a professional exposure assessment, or legally required monitoring.
