Parabolic Microphone

thingiverse

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