About
Tacet is a decibel meter and a noise log in one: measure the sound level in dB, log every incident, and hand over a PDF report when you complain about the noise.
MEASURE
• A-, C- and Z-weighted sound level (dBA/dBC/dBZ), Fast and Slow response
• Leq, Lmax, Lmin, Peak, L10 and L90 — the values noise rules refer to
• 60-second chart, colour scale from quiet to painful, keeps measuring with the screen locked
• Live Activity on the Lock Screen and in the Dynamic Island
• Calibrate once against a reference sound level meter; the offset is printed in every report
LOG
• One tap after each measurement: kind of noise (music, footsteps, voices and parties, dog, construction, traffic, machinery, doors), how it affected you (woke me up, child woken, couldn’t work…), note, place, address
• Manual entries for incidents you did not measure
• Optional audio clip with each entry, fingerprinted with SHA-256 (Pro)
NIGHT WATCH (Pro)
• Set a threshold, lock the phone and go to bed. Every disturbance above the threshold — music through the wall, footsteps upstairs, a party next door — is logged with its time, duration, level and an optional clip. In the morning you have the list for your complaint.
COMPARE
• Reference limits with sources: WHO, Russia (SanPiN), Germany (TA Lärm), England & Wales (Noise Act), France (émergence), Spain (RD 1367/2007), Italy (DPCM 1997), typical US ordinances, Toronto — or your own values
• Quiet hours per rule or your own; night entries are judged by the night limit and marked with a moon
• “Over the background” metric for rules that work with emergence
PATTERNS
• Incidents per day, weekday × hour heatmap, nights disturbed, kinds of noise, loudest and longest (Pro for 30 days, 90 days and all time)
REPORT (Pro)
• PDF: period, place, device, calibration, summary, charts, table of incidents, methodology and disclaimer
• CSV for spreadsheets; single-incident PDF from any entry
PRIVATE
• Everything stays on your device. No account, no upload, no ads, no analytics.
Tacet is not a certified sound level meter. Readings from a phone microphone are indicative; calibrate against a reference meter for the best accuracy. Reference limits are public guidance values, not a legal assessment.
Free: the full meter, calibration, limits, the diary for the last 7 days and weekly patterns. Tacet Pro: full history, night watch, audio clips, PDF and CSV reports, patterns over 30 days, 90 days and all time. Tacet Pro is available as a weekly or yearly subscription or as a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage them in Settings › Apple ID › Subscriptions.
