Condo noise complaints turn into fines and fights with weak evidence on both sides
A tenant on r/Bangkok was fined 5,000 baht for 10-15 minutes of music just before 9 PM, based on a corridor audio recording; house rules say 2,000-10,000. Another renter described repeated complaints and threats from a neighbor. On Pantip a resident said the juristic office spoke to loud neighbors and it stopped for a day or two, then returned.

5 ways to tackle it
Hardware and sensors
Decibel Puck: a sound meter that logs levels by minute and never records audio
An ESP32 puck on the wall measures loudness and logs the number and time, with no sound saved. Before 9 PM it shows green, amber near the house-rule limit. When the office says 'you were loud', the tenant has a minute-by-minute graph, and the neighbor who complains has the same graph.
Build with ESP32, I2S MEMS mic (INMP441), OLED or e-ink, Google Sheets log, 3D-printed case
Camera and vision
Rules Reader: photograph the house rules and get a one-card summary of what counts
The tenant photographs the juristic office's rules notice. Claude vision turns it into a one-page card in English, Thai or Chinese: quiet hours, the decibel or time limits and the fine range of 2,000 to 10,000 baht. It marks which things are clearly allowed so a 15-minute 8:45 PM song is not argued from nothing.

Complaint Clerk: an agent that keeps the log and writes the letter to the office
When the Puck log and the neighbor's complaints pile up, the agent drafts a calm letter to the juristic office in Thai: dates, levels, what the rules say, and a proposal for a fair fix. A tenant who is shy about conflict sends a clear, polite file.

Web portal
Door Notes: print polite note cards for your neighbor's door instead of calling the office
The user picks a situation, such as 'music after 9', 'dog barking' or 'party tonight', and a tone: friendly, firm or apologetic. The page prints a small card in Thai, English or Chinese with a drawn smiley and a way to reply. A note on the door settles most of it before the office hears.

Voice and phone
Neighbor Talk Coach: practice the awkward knock-on-the-door conversation on the phone
The user calls a number and an AI plays the neighbor who is loud or the neighbor who complains. They practice a calm opening line and get a Thai or English script to use after. People are far more likely to knock if they have rehearsed once.
Build with Twilio Voice, Whisper, Claude, Thai and English TTS
