dBcheck is an Android app for measuring everyday sound, following noise exposure over time, and comparing personal hearing checks with your own baseline. Press Listen to see the page demo respond to the film behind it.

Traffic, open offices, cafés, the gym: everyday noise adds up, and ears are terrible at keeping score. dBcheck quietly counts it for you, so “it wasn’t that loud” becomes a number instead of a guess.
44.1 kHz audio sampling, RMS → dB conversion with LAeq energy averaging, 1-second persistence cadence, and weekly exposure analytics computed from your real sessions.
A single level cannot describe exposure on its own. dBcheck combines level and duration to help you follow how an estimated noise dose accumulates over time.
A real dosimeter with NIOSH REL and OSHA PEL standards: TWA, live dose, projected dose and estimated remaining exposure time, plus threshold and 85 dB peak alerts on your own schedule.
Nighttime sound can be difficult to place from memory. The sleep monitor shows when notable noise events occurred and how loud they were, without claiming to know what woke you.
Overnight measurement with notable-event detection, equivalent level and LCpeak stats, loud-period summaries and a morning insights view tied to each sleep session.
dBcheck lets you run a personal threshold check and compare results with your own earlier baseline. It is designed for relative tracking, not a clinical hearing test or diagnosis.
A Hughson-Westlake style threshold test, plus a short recovery check at 1/4/8 kHz that measures shifts against your baseline. Personal tracking, not a medical diagnosis.

A whisper is quiet at close range. Distance and room reflections can change the reading substantially.
Usually well below occupational exposure limits.
A whisper is quiet at close range. Distance and room reflections can change the reading substantially.
Usually well below occupational exposure limits.
Normal conversation varies with vocal effort, distance, background noise and room acoustics.
Ordinary one-to-one conversation is generally not treated as a hearing hazard.
Read sound guideVacuum cleaner readings change with the model, setting, floor, room and microphone position.
Duration matters more for repeated or occupational cleaning than for a short household task.
Read sound guideRoad traffic changes with vehicle mix, speed, distance and surrounding buildings.
Long or repeated exposure near the upper end deserves attention.
Powered mower levels vary with the machine, blade, load, terrain and operator position.
Levels in this range can accumulate occupational noise dose quickly.
Read sound guideConcert levels vary by audience position, loudspeaker layout, venue, programme and averaging period.
At higher average levels, a full occupational reference dose can accumulate rapidly.
Read sound guideCrying levels vary strongly with age, vocal effort, distance, room and whether average or maximum is reported.
A close loud cry and repeated exposure are different contexts; the reading cannot assess health.
Read sound guideSirens are designed to remain audible over other sound and can be intense at close range.
Move away from the source when practical; distance strongly affects the level.
Fireworks produce brief impulse peaks. Type, distance and surroundings create large variations.
Impulse sound is not well represented by a simple continuous-exposure estimate.
Typical ranges vary with distance, environment, source and measurement method.

Measurement & analysis
On-device YAMNet classification names what the meter hears (speech, music, traffic) without recording audio.
Audio analysis and app data are on-device and no account is required. Optional Health Connect features can share supported session data when the user explicitly enables them. Raw audio is not uploaded for analysis.
dBcheck for Android is in final tuning before release.
The observatory opens soon on Google Play.
