So my 3yo is already butting heads with me over volume. Doesn't want to wear hearing protection any more. Says, "I want to play my drums loud!" My rule was acoustic guitars and electronic drums are ok without hearing protection. For acoustic drums we need to wear them. Usually he refuses, we stop playing, he pitches hissy fit. (He's getting better about that. He really is a good kid, but he's 3)
So I was joking on another forum about a stoplight, and found they make such a device for classrooms. Runs about $100. Yikes. (Also, I don't like their rules for my application) But, as it turns out, I have a plastic stoplight about 12" tall sitting in the closet, and a bunch of microcontrollers in a drawer. Just bought a bunch of LED (easier/cheaper to drive directly from microcontroller pins), and bought a little electret mic/preamp board off ebay. Total outlay for stuff I didnt already have sitting around, like $15.
I showed him the stoplight, told him the new rule. He appears very interested in the stoplight, so I'm hoping this works. Still waiting on the mic board, but I worked some on the controler code this weekend. Basically it works like this:
< 85 db - Light is green
> 85 db - Light is solid yellow. Hearing Protection Required (Takes about 30 seconds to clear, may go up to 5min or so)
> 105 db -Red light also comes on (yellow stays on). Too Darned Loud. Takes about 2 seconds to clear once you drop below 105.
I'm still waiting on my sound board to arrive, but I'm hoping to get my LED's wired up, replace the 120v bulbs & wiring, and drive it off serial commands for now. It kinda started as a joke, I'm optimistic that it'll help with compliance here, but like... everyone needs one of these in their rehearsal space. (Our limits are kinda strict cause he's so little.)
