Has it been difficult to explain inter-floor noise in words?
Decilog is a noise log app that automatically measures and records, via smartphone, when, how often, and at what time of day noise occurred.
Show us with data instead of making vague appeals.
■ Real-time dB(A) Measurement + Waveform
Displays sound intensity in real-time decibels and waveforms.
Automatically detects loud moments as events based on legal thresholds.
■ Automatic Event Recording + Playback
Automatically saves segments that exceeded the threshold along with the time of occurrence, duration, and maximum dB.
Each event can be listened to again along with a dB(A) time-series graph, and you can leave contextual notes such as "thumping" or "furniture dragging."
■ Statistics at a Glance
· Calendar Heatmap — Noise distribution by day of the week × time of day
· Graph showing occurrence distribution by time of day
· Nighttime (22:00–06:00) ratio and count of exceedances
· Acoustic metrics such as Lmax / Leq / L10 / L90
■ Export & Share Reports
Export as Excel (CSV) or PDF reports, and share directly via a browser on the same Wi-Fi network.
■ Privacy-Protecting Measurement
Provides low-quality, bandwidth-limited recording by default, making conversation identification difficult.
This app is not intended for transcribing conversations and respects the Communications Secrets Protection Act.
■ Flexible Measurement Modes
· Manual — Start/stop manually when needed
· Scheduled — Repeat measurement at set times
· Always — 24-hour measurement
You can also reduce battery strain by setting the device to measure only while charging.
■ Notice
Since smartphone microphones are not calibrated sound meters, the measured dB values are not legally established evidence but are 'supplementary reference materials.' We recommend using the records from the Dashlog as supporting documentation when explaining to neighbors, apartment management offices, or complaint centers, "Noise is occurring in this pattern, so I request official measurements."
If more accurate measurements are required, a microphone sensitivity calibration function is also provided.
