Parabolic Microphone, 340mm

thingiverse

A larger version of a parabolic mic, much improved acoustics vs. my prior model. Prints well on a 200x200mm bed. Print it relatively solid, since sound reflects better off hard surfaces. You will need several M3 5mm screws, four M3 20mm screws, locking M3 nuts, and a lapel microphone. Test 1: Small stream waterfall. First 10 seconds are with just a microphone. Last 10 seconds are with the parabolic mic setup. The difference is dramatic. https://youtu.be/C6U8m3roYoE Test 2: Witness the disgusting self-hygiene sounds of the pug. The first 10 seconds were recorded through the parabolic mic, and the last 8 seconds with just the lapel mic: https://www.youtube.com/watch?v=2isji7mE3Ik
