The best way to document nuisance noise.

Note each time noise disturbs you, see how often it really happens, and export a clear PDF report.

Free to use. The audio stays on your phone.

Why keep a noise log

Noise is hard to describe after the fact. Was it every evening, or twice last week? Ten minutes, or an hour? Memory blurs, and impressions are hard to share.

A simple log turns what you experience into plain facts. That makes it easier to understand for yourself, and easier to talk about calmly. Often the people around you simply don't realise how far sound carries, and a factual summary is a friendly way to show them.

See how often it really happens, and at what times.
Replace impressions with dates, durations and levels.
Start a conversation with facts, not frustration.

How Noisance works

Log the moment

When noise disturbs you, tap Record. A live level meter shows what the phone is picking up. The recording stays on your phone and is never uploaded.

See the pattern

Pick a period - the last 7, 30 or 90 days, or your own dates - and see how many events there were, how long they lasted and how loud they were, compared with the period before. Open any entry for its waveform, spectrogram, exact start and end times, and the recording itself.

Export a summary

One tap produces a PDF: a summary page with the headline figures and charts - events over time, time of day by weekday, sound levels - followed by the full log with spectrograms and times. Every page is stamped with the date and time it was generated. Keep it for yourself, or share it with whoever you choose.

What's in the app

From the first tap to the finished summary.

Noisance Review screen: 23 events over 30 days with average duration, average and loudest level, each with its change versus the previous period, above a list of events and an Export PDF report button. — ReviewYour log for any period, with the number of events, their average duration and sound levels, and how they compare with the period before.

Noisance Event detail screen: amplitude waveform and spectrogram of a 38-second recording, audio playback controls, and statistics with start time, end time, duration and sound level. — Event detailWaveform, spectrogram, minimum, mean and maximum level, exact start and end times, and playback.

First page of a Noisance PDF report: headline figures for 23 events over 30 days, a chart of events over time, a time-of-day by weekday heatmap, a sound-level histogram, and a generation stamp. — PDF reportA summary page with charts, then the full log. Every page carries a generation stamp.

Who's behind Noisance

Bobinette.net is a digital studio in the south of France, working for clients worldwide including Google and Meta. Noisance is an app that started off with a personal side-project. We've decided to develop it fully to make it available to everyone.

Development

“Noisance began with a noisy dog that was bothering me over a long period. I wanted to understand it properly - how often, how long, how loud - rather than just be annoyed by it. I hope it's helpful for others too!”

Arpad is a creative technologist and developer with over 25 years' experience, working on everything from artistic installations to backend systems for Google.

Data visualization has become a particular passion, with several recent projects bridging the gap between data and art, including an installation at the Victoria & Albert Museum's new V&A East Storehouse building in London.
