Building the Ultimate Super Low Self-Noise DIY Microphone

Matthew Perks from the popular youtube DIY channel DIY Perks recently published an interesting video on an ambitious DIY project to build an ultra low noise microphone for recording different ambient sounds – the result is quiet astonishing.

So let’s say that you want to record all sorts of sounds from sea waves crushing ashore to the sounds of the wind in the trees and even (and we still find this hard to believe – but you can check it out for yourselves in the last part of the video), a beating heart from a few centimeters away!

Like many of Matt’s other projects – this is not an easy build and if you are not knowledgeable about electronics there is very little chance that you will be able to accomplish something similar, however even if not – it is still a hack of a lot of fun to watch – so site back and enjoy and listen to the finished microphone with some good earphones to really hear the sound quality.

Here are the preamp schematics that Matt used. In case you were wondering new Rode NT1-a mic that Matt used for this build (he got two of them second hand and took them apart), cost about $230 each, the rest of the built is fairly inexpensive.
