Few things are more annoying than being at a conference and having an inconsiderate group conducting a vociferous sidebar that drowns out the speaker. More annoying still is the inevitable shushing; nobody likes being either the shusher or the shushed. So why not take the humans out of the loop and automate the chore of keeping the peace?
Such was the challenge presented to [BotBerg] before a recent conference, who came up with this automated shusher (translation) on short notice. The build is based on the Arduino Nano 33 BLE Sense Deck, a sensor-rich dev board that’s perhaps a little overkill for the job, but hey — you roll with what you’ve got. The board’s MEMS microphone is the sensor used here, which measures the ambient sound pressure level multiple times per second. When the background noise exceeds a potentiometer-set threshold, an MP3 player is triggered to play a sound clip entreating the offenders to pipe down. The whole thing is housed in a playful 3D-printed enclosure shaped like a mouth, which should be sufficient reminder alone to keep yours shut.
This was a quick-and-dirty prototype, of course, and probably could use some refinement. Given the behavior we’ve witnessed at some conferences, we’d say hooking it up to a Nerf turret gun would be a justifiable escalation.

A servo to raise a 3D printed forefinger (and hand) to the 3D printed lips!
Another finger may be substituted for repeat offenders.
now use machine learning to track the person speaking from a overhead camera and shush them after say 2 minutes.
I would make another one to reply and say ‘No!’.
How does it know that the conference call trumps whatever else is going on.
It shouldn’t have to. If your sidebar is more pressing, mute your mic or drop from the con call. Why would anyone assume their side convo is more important than other’s ability to hear the conference call they are there for?
To be clear, this is not at all about conference calls or online meetings. This is about physical conferences with a stage and such.
I gave my local library the Librarian Action Figure of world famous librarian Nancy Pearl a few years ago.
Perhaps I should borrow it back and add this function to it?, after I automate the arm motion?
If one could somewhat get the direction of the sound, one could add some directional speaker with it and it would be an amazing device (commercial even) to shush people without bothering others even with the shush 🤫
