Quelle est la principale nuisance sonore à Paris ? Les sirènes de POLICE.

J'ai codé un détecteur de sirènes (en GO, sur Raspberry Pi Zero + micro I2S MEMS) et l'ai placé boulevard Beaumarchais pendant 163 jours (fin septembre à mi-février).

Résultats sur 5 728 passages détectés (35/jour en moyenne) :
🚔 Police : 77,3%
🚔 Gendarmerie : 4,2%

👉 Total forces de l'ordre : 81,5% (4 670 sirènes)

🚒 Pompiers : 9,7% (554)
🚑 SAMU : 8,8% (504)

Bienvenue dans l'état policier sonore. 😱

@stan I hear you (no pun intended) but still, Paris is quiet in relative terms (I’m here now and I adore walking all these car-free or low traffic streets). Your mayor is a dream and she did an awesome job (we could use her in Lisbon!)

When I lived in Vancouver I did something similar to you with a Pi on my balcony but detecting loud engines. This is a sample of the most quiet days. I actually sent this to some of the city council members. No one ever answered back. https://youtu.be/GniLgst2D04?si=lF-oLcBWywxtSUO1

The problem is the police, not the mayor ;-)
I sincerely doubt that policemen and officials need sirens so often

@stan They likely don’t. But at least in Europe they use urban sirens. In Canada all the sirens are made for open road, and they use them in cities anyway. I had to cover my ears when I was in the street and emergency vehicles went by because the sound caused physical pain on my ear drums. 😖 Still, it’s something to improve here as well. Sirens are only loud because we tolerate drivers inside their noise insulated vehicles. For them to hear, everyone else suffers.
