It's going to work, but not as good. I have a friend who is an electronics expert who said that even 1G resistor is actually not too good and it is recommended to use even higher value resistor. It

nice inexpensive solution. which aom 5024 version is yours? I've got a pair of 5024 with naked metallic front side with some pinhole perforation on it. I know there is also aom 5024 with felt or

Casey - My wonderful, funny wife thought of this even before I finished putting everything together.

Sounds great! But it's not done until it has a couple of googly eyes (helps with HF dispersion). :-)

I love it! Best Regards, Jules Ryckebusch

Sample recording from my garden. Birds, a bit of LF hum (on and off) from neighbour's lawn mower and me, at the end, walking around the mic. https://on.soundcloud.com/v3Wc9pAuJqq5Lvhx9

Inspired by tree ears concept and having it tested in few setups I decided to make a permanent fixture. I found myself a roughly head-sized log, bought silicon ears from Ali as well as a connector box

That was not clear in your post. The equivalent voltage of an electret mic is close to 100V, so 1V is negligible. t should be less than a fraction of dB. >

The purpose of that 1Meg pot is to bias the FET properly. I do this in my "Pimped Alice" circuit. The addition (or subtraction depending on polarity of the capsule pre bias) is negligible for

There was some discussion a while back about deliberately adding external polarization to an electret to try to influence its SPL handling.? So probably no big effect with just one volt. -Scott --

The capsule needs no current to operate as it does not have a FET. In fact, if I connect it to an oscilloscope with 10x probes (10MegOhm input impedance) and speak loudly into it, I see almost 200 mV

"This effectively attempts to polarize a pre-polarized electret capsule by 1 volt or so." No. The available current is in the order of nA, so the capsule will not work. You need to power the capsule

I am a newbie in terms of mic building and modding, I have studied electronics in university, but have done only digital design for about 15 years now. I am trying to design (for fun) a different

Yup, your understanding was right.? But of course, you could still first try 750 MOhm and only if you're not happy with the LF noise, then try to get 1 or 2 GOhm resistors. The human ear is not very

@jp8 If I understand you correctly, the sum total of noise in the audible band is reduced with a larger resistor value, so I should try to get 1G if possible. Unfortunately there's some availability

Ah great thank you

Yes, you can, like Jules already said. But not only will the LF cutoff point move to a higher frequency. LF noise will also increase, because with every doubling of the resistance, the resistor's

Yes a 750M will work. Anything above 200-300M will work. Actually 100M will work you start to get a 3dB down point in the audio range below 200M Best Regards, Jules Ryckebusch

I cant get a 1 gig ohm resistor but i can get a 750M. I can also series 2x 500M but that will complicate things and be difficult. Here's a schematic for reference thank you
