A sound-level meter and noise dosimeter that measures live decibels, tracks work-shift exposure, and analyzes frequency bands.

Landing page captured for the 2026-09-04 issue.

Field notes

The app turns microphone input into both instantaneous readings and accumulated exposure records. Users can choose among OSHA, NIOSH, and NOM-011 criteria, inspect a 31-band 1/3-octave analyzer, and apply a calibration offset from a 94 dB reference or trusted meter. History stores sessions and spectrum captures, while the site says reports can be exported as PDFs and data can sync through the user's iCloud.
