... I read somewhere that the human ear can detect impulses that, if they were a sustained waveform, would be well above 20 kHz and possibly into the 30 kHz...
I'll try to make this at a level which is more or less accessible to all. In order to measure microphone frequency response, it is necessary to have two...
I would like to make some binaural mics for my DV camcorder (Canon DV60) as an experiment. I am sure the thing doesn't supply power to the mic input jack, so I...
I built a pair of WM61A mics, using the 2 wire Linkwitz mod. All I did was solder wires on the back and put a dab of epoxy to seal the back and secure the...
The primary noise source in the WM60 is the Brownian motion in the air layer on the diaphragm. Just for fun I Googled "brownian motion"+air and among the bones...
Thanks to Mark, I received 10 sample JLI capsules. These are nearly identical in size and appearance to the WM60. I modified five of them by cutting the two...
Hi, sorry to post again. I have been looking at Knowles Electronics' FG series microphones, and they look pretty good. There are two types, a 30 db max self...
... We live in such a noisy world it's a commonly held belief that we are safe at fairly high levels. That you have not worked in the even noisier environments...
Hi, I'm interested in building a couple of omnis for recording a large church organ. Should I stock up on the panasonics before they run out, or should I try...
The 61s are about 7 db more hotter than the WM-60s. Are these suitable replacement for loud enviroments like live music? I have used these in the past with...
Its official. All WM-60A microphone capsules are being discontinued as of March 2004. I just got the bad news directly from Digi-Key. Below is what they...
No, I haven't eliminated anything as far as directional or size. Someone was interested in better 55's, others in 1/2", etc. All are interesting. I must...
Hey all-- This reminded me of a question I meant to ask long ago: is the response/performance/accuracy of a mic/diaphragm affected by lots of use at high spl's...
Hello to all. I am a new member, and have some thoughts. So far I've built some ribbon and LD tube mics. Last night, just out of curiosity I took apart...
If there is enough interest in having ECM manufacture a replacement for the WN60/61 capsule. Then how about manufacturing a capsule that could be used in a RF...
... resonance frequency. ... performance -- dunno. ... know the equation? My advice is to not mess with the hole in the front cavity. The properties of the...
i would like to see it in two sizes one as small as possible, and the other about 1/2 diameter.The small one as omni, and the larger one both omni and ...
I would like pc mount wires coming out of it so I can build an array of a dozen quickly. Arranged so they would plug right into a solderless or solder...
I recently ran across a microphone capsule that appears to keep its fet a few inches outside of the capsule. If there is no downside to that design I could see...
Hi, mstrong. I record church music, choral works and loud pipe organ. My WM55 XY mic is useful because it's diminuative enough not to intrude on the service....
From: "Rich Peet" <richpeet@...> ... I do nature recording, and would agree in general. However, I'd like to experiment with RF mics with diaphragms...
I am uploading some photos of designs i currently use. Upload in progress as I have to find some of the photos. I will get to my electrical designs with time...
We make many kinds of ECM's It's time the WM-60/61 had some competition. If everyone can agree on what such a device ought to be, I'll run some, pass them out...
