My mom got me an electric lighter for Christmas and when I turned it on my son freaked out. Apparently it makes an annoying high pitched sound that adults can't hear, so I thanked her for the excellent punishment rod. 😈
Ok yeah that is actually pretty loud. This is the power spectrum with the tip held about an inch away from the microphone. Going "aah" at the same microphone from the same distance at a normal or slightly elevated speaking level is giving me peaks around -40 and this thing is doing -20.
@pganssle Damn! Good investigation.
I think it is this one, in case anyone wants to... uh... light candles 😉 https://www.amazon.com/VEHHE-Electric-Rechargeable-Flexible-Barbecue/dp/B0852VJ6RD
