Parabolic Microphone

thingiverse

Significantly increases volume of recorded sound from the direction it's pointed in. My phone app measured average dB of radio news at 50 without the parabola and 56 with it. Just as importantly, it greatly reduces sound capture not coming from the intended direction. The effect is a far greater ability to discern the intended sounds. Designed for this lapel mic: http://a.co/1vnyzRc ...but will probably work with any lapel mic. You will want to slide the arm in and out until you find the best focal point for your mic. Then tighten in place with an M3 screw. You'll also need three M3 10mm screws to attach the handle. Feel free to edit your own version. Those with large printers could make a truly impressive device: https://www.tinkercad.com/things/jyTTYqwkgOV
