One of the hazards of both our Wood Shop and our Metal Shop is that of potential ear-damaging noise. I’d like to see us make both of those shops a little safer by designing a Dangerous Noise Level warning system. The idea would be to have a device in each shop that monitors sound levels, and then lights up or flashes a warning when the sound reaches a level that could potentially cause hearing damage. At its most basic, it would be a microphone connected to a microcontroller (Arduino or other) that would trigger a relay to start a flashing amber warning light that could be seen throughout the shop.
I’d like to hear ideas on getting this accomplished. The sign itself could be made on the CNC plasma, Shopbot, laser, vinyl cutter, foam cutter, or even another way. We can build a revolving amber light, or simply order one on Amazon for next to nothing.
While it is true that our members are ultimately responsible for using hearing protection when needed, I think it is likely that more folks would think to put on a pair of hearing protectors or ear plugs if the light were there to remind them.
Your thoughts? Ideas? Go!
